    Full Text Available The automotive sector is characterised by a relatively low trade/salesratio. While the production of most automotive producers in the world is spread over variouscountries in the value chain, the brands are still considered to reflect some national identity.Internationalisation strategies may change over the lifecycle of the product and automakerstend to pursue diametrically opposed strategies. In mature markets, it is about managing whatgoes on beneath a static surface; in emerging markets’ dynamic environments, companies muststrategically position themselves to benefit from growth opportunities. However, without theright strategy and execution in mature markets, it is clear that traditional OEMs cannot profitfrom emerging markets-the persistence of structural issues in mature market operationseventually will rob all but the most resilient competitors of the opportunity to compete inemerging markets.

    Full Text Available Two major drivers for the use of newer steels in the automotive industry are fuel efficiency and increased safety performance. Fuel efficiency is mainly a function of weight of steel parts, which in turn, is controlled by gauge and design. Safety is determined by the energy absorbing capacity of the steel used to make the part. All of these factors are incentives for the U.S. automakers to use both Highly Formable and Advanced High Strength Steels (AHSS to replace the conventional steels used to manufacture automotive parts in the past. AHSS is a general term used to describe various families of steels. The most common AHSS is the dual-phase steel that consists of a ferrite-martensite microstructure. These steels are characterized by high strength, good ductility, low tensile to yield strength ratio and high bake hardenability. Another class of AHSS is the complex-phase or multi-phase steel which has a complex microstructure consisting of various phase constituents and a high yield to tensile strength ratio. Transformation Induced Plasticity (TRIP steels is another class of AHSS steels finding interest among the U.S. automakers. These steels consist of a ferrite-bainite microstructure with significant amount of retained austenite phase and show the highest combination of strength and elongation, so far, among the AHSS in use. High level of energy absorbing capacity combined with a sustained level of high n value up to the limit of uniform elongation as well as high bake hardenability make these steels particularly attractive for safety critical parts and parts needing complex forming. A relatively new class of AHSS is the Quenching and Partitioning (Q&P steels. These steels seem to offer higher ductility than the dual-phase steels of similar strengths or similar ductility as the TRIP steels at higher strengths. Finally, martensitic steels with very high strengths are also in use for certain parts. The most recent initiative in the area of AHSS

The objective is to study the Quantitative Performance of Chennai Automotive Industry Cluster before (2001-2002) and after the CDA (2008-2009). The methodology adopted is collection of primary data from 100 ACI using quantitative questionnaire and analyzing using Correlation Analysis (CA), Regression Analysis (RA), Friedman Test (FMT), and Kruskall Wallis Test (KWT).The CA computed for the different set of variables reveals that there is high degree of relationship between the variables studied. The RA models constructed establish the strong relationship between the dependent variable and a host of independent variables. The models proposed here reveal the approximate relationship in a closer form. KWT proves, there is no significant difference between three locations clusters with respect to: Net Profit, Production Cost, Marketing Costs, Procurement Costs and Gross Output. This supports that each location has contributed for development of automobile component cluster uniformly. The FMT proves, there is no significant difference between industrial units in respect of cost like Production, Infrastructure, Technology, Marketing and Net Profit. To conclude, the Automotive Industries have fully utilized the Physical Infrastructure and Centralised Facilities by adopting CDA and now exporting their products to North America, South America, Europe, Australia, Africa and Asia. The value chain analysis models have been implemented in all the cluster units. This Cluster Development Approach (CDA) model can be implemented in industries of under developed and developing countries for cost reduction and productivity

    The 'Change in the Automotive Industry' investigation was initiated by the Swedish Energy Agency in the autumn of 2000. The objective has been to illuminate and analyse technical developments in respect of the use of electricity in vehicles, not only for various ancillary systems but also for propulsion. A number of Swedish businesses that have, or could have, links with the automotive industry have been investigated. The main aim has been to attempt to identify the opportunities for the industry to meet and benefit from the changes. A total of 14 businesses have been visited, and a further 29 companies have replied to a survey questionnaire on the theme. Business intelligence shows that a great deal of work is being done on the use of electricity for automotive propulsion, in everything from battery vehicles, via electric hybrid vehicles to fuel cell vehicles. In terms of development, the Japanese manufacturers are in the lead, while the USA constitutes the largest single driving force behind development. The technical development requires a greater understanding within several new disciplines, and leads to major changes between different industry sectors. The results show that Sweden possesses world class expertise in several of the fields that can become very important for tomorrow's automotive industry. At the same time, the companies expect difficulties in recruiting personnel qualified in the appropriate disciplines, such as development and design. There is, therefore, a clear risk that the present-day expertise will progressively fade away if nothing is done.There is a wide range of awareness of the greater use of electricity in vehicles. However, in principle, all companies feel that development towards new drive trains will proceed rapidly. Most of the companies are also very interested in descriptions and analyses of the state of development. The general conclusion of the work is that there are excellent prospects for Swedish industry to

In the year 2004-2005 under the cluster development approach (CDA), they formed Chennai auto cluster, under public private partnership concept, received grant from Government of India, Government of Tamil Nadu, Ambattur Municipality, bank loans and stake holders. This results development in infrastructure, technology, procurement, production and marketing interrelationships among ACI. The objective is to determine the correlation coefficient, regression equation, technical efficiency, peer weights, slack variables and return to scale of cluster before and after the CDA. The methodology adopted is collection of primary data from ACI and analyzing using data envelopment analysis (DEA) of input oriented Banker-Charnes-Cooper model. There is significant increase in correlation coefficient and the regression analysis reveals that for one percent increase in employment and net worth, the gross output increases significantly after the CDA. The DEA solver gives the technical efficiency of ACI by taking shift, employment, net worth as input data and quality, gross output and export ratio as output data. From the technical score and ranking of ACI, it is found that there is significant increase in technical efficiency of ACI when compared to CDA. The slack variables obtained clearly reveals the excess employment and net worth and no shortage of gross output. To conclude there is increase in technical efficiency of not only Chennai auto cluster in general but also Chennai auto components industries in particular.

    2004-06-01

    The trend in the automotive industry towards new advanced high strength steels (AHSS), combined with the ongoing reduction in program lead times have increased the need to get tool designs right, first time. Despite the fact that the technology used by sheet metal stamping companies to design and manufacture tooling is advancing steadily, finding optimal process parameters and tool geometries remains a challenge. Consequently, there has been a transition from designs based largely on trial and error techniques and the experience of the stamping engineer, to the increased use of virtual manufacturing and finite element (FE) simulation predictions as an indispensable tool in the design process. This work investigates the accuracy of FE techniques in predicting the forming behavior of AHSS grades, such as TRIP and dual phase, as compared to more commonly used conventional steel grades. Three different methods of simulation, one-step, implicit and explicit techniques, were used to model the forming process for an automotive part. Results were correlated with experimental strain and thickness measurements of manufactured components from the production line.

    Chennai, also called the Detroit of India, is India's second fastest growing auto market and exports auto components and vehicles to US, Germany, Japan and Brazil. For inclusive growth and sustainable development, 250 auto component industries in Ambattur, Thirumalisai and Thirumudivakkam Industrial Estates located in Chennai have adopted the Cluster Development Approach called Automotive Component Cluster. The objective is to study the Value Chain, Correlation and Data Envelopment Analysis by determining technical efficiency, peer weights, input and output slacks of 100 auto component industries in three estates. The methodology adopted is using Data Envelopment Analysis of Output Oriented Banker Charnes Cooper model by taking net worth, fixed assets, employment as inputs and gross output as outputs. The non-zero represents the weights for efficient clusters. The higher slack obtained reveals the excess net worth, fixed assets, employment and shortage in gross output. To conclude, the variables are highly correlated and the inefficient industries should increase their gross output or decrease the fixed assets or employment. Moreover for sustainable development, the cluster should strengthen infrastructure, technology, procurement, production and marketing interrelationships to decrease costs and to increase productivity and efficiency to compete in the indigenous and export market.

    2001-01-01

    Fiber optics are finding a place in the automotive industry. Illumination is the primary application today. Soon, however, fiber optics will be used for data communications and sensing applications. Silica fiber optics and plastic fibers are sufficient for illumination and communication applications however, sensing applications involving high temperature measurement and remote gas analysis would benefit from the use of infrared fiber optics. Chalcogonide and heavy metal fluoride glass optical fibers are two good candidates for these applications. Heavy metal fluoride optical fibers are being investigated by NASA for applications requiring transmission in the infrared portion of the electromagnetic spectrum. Zirconium-Barium-Lanthanum-Aluminum-Sodium-Fluoride (ZBLAN) is one such material which has been investigated. This material has a theoretical attenuation coefficient 100 times lower than that of silica and transmits into the mid-IR. However, the measured attenuation coefficient is higher than silica due to impurities and crystallization. Impurities can be taken care of by utilizing cleaner experimental protocol. It has been found that crystallization can be suppressed by processing in reduced gravity. Fibers processed in reduced gravity on the KC135 reduced gravity aircraft were found to be free of crystals while those processed on the ground were found to have crystals. These results will be presented along with plans for producing continuous lengths of ZBLAN optical fiber on board the International Space Station.

    2016-08-01

    Measurement System Analysis (MSA) is a critical component for any quality improvement process. MSA is defined as an experimental and mathematical method of determining how much the variation within the measurement process contributes to overall process variability and it falls into two categories: attribute and variable. Most problematic measurement system issues come from measuring attribute data, which are usually the result of human judgment (visual inspection). Because attributive measurement systems are often used in some manufacturing processes, their assessment is important to obtain the confidence in the inspection process, to see where are the problems in order to eliminate them and to guide the process improvement. It was the aim of this paper to address such a issue presenting a case study made in a local company from the Sibiu region supplying products for the automotive industry, specifically the bag (a technical textile component, i.e. the fabric) for the airbag module. Because defects are inherent in every manufacturing process and in the field of airbag systems a minor defect can influence their performance and lives depend on the safety feature, there is a stringent visual inspection required on the defects of the bag material. The purpose of this attribute MSA was: to determine if all inspectors use the same criteria to determine “pass” from “fail” product (i.e. the fabric); to assess company inspection standards against customer's requirements; to determine how well inspectors are conforming to themselves; to identify how inspectors are conforming to a “known master,” which includes: how often operators ship defective product, how often operators dispose of acceptable product; to discover areas where training is required, procedures must be developed and standards are not available. The results were analyzed using MINITAB software with its module called Attribute Agreement Analysis. The conclusion was that the inspection process must

    Composite materials loom large increasingly important role in the overall industry. Composite material have a special role in the ever-evolving automotive industry. Every year the composite materials are used in a growing number of elements included in the cars construction. Development requires the search for ever new applications of composite materials in areas where previously were used only metal materials. Requirements for modern solutions, such as reducing the weight of vehicles, the required strength and vibration damping characteristics go hand in hand with the properties of modern composite materials. The designers faced the challenge of the use of modern composite materials in the construction of bodies of power steering systems in vehicles. The initial choice of method for producing composite bodies was the method of molding injection of composite material. Molding injection of polymeric materials is a widely known and used for many years, but the molding injection of composite materials is a relatively new issue, innovative, it is not very common and is characterized by different conditions, parameters and properties in relation to the classical method. Therefore, for the purpose of selecting the appropriate composite material for injection for the body of power steering system computer analysis using Siemens NX 10.0 environment, including Moldex 3d and EasyFill Advanced tool to simulate the injection of materials from the group of possible solutions were carried out. Analyses were carried out on a model of a modernized wheel case of power steering system. During analysis, input parameters, such as temperature, pressure injectors, temperature charts have been analysed. An important part of the analysis was to analyse the propagation of material inside the mold during injection, so that allowed to determine the shape formability and the existence of possible imperfections of shapes and locations air traps. A very important parameter received from

    Removal of polycyclic aromatic hydrocarbons (PAHs) existed in automotive industry treatment sludge was examined by considering the effects of temperature, UV, titanium dioxide (TiO2) and diethyl amine (DEA) in different dosages (i.e., 5% and 20%) in this study. Application of TiO2 and DEA to the sludge samples in ambient environment was studied. Ten PAH (Σ10 PAH) compounds were targeted and their average value in the sludge was found to be 4480 ± 1450 ng/g dry matter (DM). Total PAH content of the sludge was reduced by 25% in the ambient air environment. Meteorological conditions, atmospheric deposition, evaporation and sunlight irradiation played an effective role in the variations in PAH levels during the tests carried out in ambient air environment. Moreover, it was observed that when the ring numbers of PAHs increased, their removal rates also increased. Total PAH level did not change with the addition of 5% DEA and only 10% decreased with 5% TiO2 addition. PAH removal ratios were 8% and 32% when DEA (20%) and TiO2 (20%) were added, respectively. It was concluded that DEA was a weak photo-sensitizer yet TiO2 was effective only at 20% dosage.

    Full Text Available The acceptance of corporate sustainability implementation and sustainability reporting has continued to grow steadily in recent years. This is particularly true for companies in the automotive industry. Increasing regulatory demands, for example, with respect to CO2 emissions, are one clear reason for this. In this paper the sustainability reports of 14 manufacturers in the European automotive industry are analyzed with respect to issues of corporate sustainability implementation. This entails content analysis of sustainability reports from 2012, and of their earliest available equivalents. The analysis of corporate sustainability implementation in the selected companies is provided with the purpose to help understand how manufacturers in the European automotive industry implement corporate sustainability. Results confirm the importance of specific policy instruments in implementation, such as the use of environmental management systems and standards, and of related changes in organizational structures. The latter include suitable adaptation of corporate strategy, philosophy, objectives, measures, and activities, as well as the need to integrate stakeholders in the adjustment process. The analysis shows that while companies are well-aware of the significance of sustainability for their industry, some tend to be leaders, and others laggards, as far as implementation is concerned.

    The need of more accurate measurements in different stages of industrial applications, such as designing, producing, installation, and etc., is the main reason of encouraging the industry deputy in using of industrial Photogrammetry (Vision Metrology System). With respect to the main advantages of Photogrammetric methods, such as greater economy, high level of automation, capability of noncontact measurement, more flexibility and high accuracy, a good competition occurred between this method and other industrial traditional methods. With respect to the industries that make objects using a main reference model without having any mathematical model of it, main problem of producers is the evaluation of the production line. This problem will be so complicated when both reference and product object just as a physical object is available and comparison of them will be possible with direct measurement. In such case, producers make fixtures fitting reference with limited accuracy. In practical reports sometimes available precision is not better than millimetres. We used a non-metric high resolution digital camera for this investigation and the case study that studied in this paper is a chassis of automobile. In this research, a stable photogrammetric network designed for measuring the industrial object (Both Reference and Product) and then by using the Bundle Adjustment and Self-Calibration methods, differences between the Reference and Product object achieved. These differences will be useful for the producer to improve the production work flow and bringing more accurate products. Results of this research, demonstrate the high potential of proposed method in industrial fields. Presented results prove high efficiency and reliability of this method using RMSE criteria. Achieved RMSE for this case study is smaller than 200 microns that shows the fact of high capability of implemented approach.

    Full Text Available The competitive nature of the contemporary business scenario requires productivity‐driven organizations to be aware of the efficiency level of their dealers. The recent economic and financial crisis has highlighted the need for effective evaluation methods going beyond the limits of traditional performance assessment methodologies in the retail industry. The automotive industry is no exception to this logic. In this sector, traditional methods are often based only on market share performances, ignoring the key role of input‐output ratios on the overall productivity of the parent company. Following this lead, in this paper we propose a method to evaluate the performance of dealerships taking into account both their market share performances and their efficiency. In order to assess dealership efficiency we use the DEA technique, and apply the proposed methodology to a multinational automotive company considering its Italian dealer network.

    Subjectivity usually causes large fluctuations in evaluation results. Many scholars attempt to establish new mathematical methods to make evaluation results consistent with actual objective situations. An improved catastrophe progression method (ICPM) is constructed to overcome the defects of the original method. The improved method combines the merits of the principal component analysis' information coherence and the catastrophe progression method's none index weight and has the advantage of highly objective comprehensive evaluation. Through the systematic analysis of the influencing factors of the automotive industry's core technology capacity, the comprehensive evaluation model is established according to the different roles that different indices play in evaluating the overall goal with a hierarchical structure. Moreover, ICPM is developed for evaluating the automotive industry's core technology capacity for the typical seven countries in the world, which demonstrates the effectiveness of the method.

    Full Text Available Polishing is a highly skilled manufacturing process with a lot of constraints and interaction with environment. In general, the purpose of polishing is to get the uniform surface roughness distributed evenly throughout part’s surface. In order to reduce the polishing time and cope with the shortage of skilled workers, robotic polishing technology has been investigated. This paper studies about vision system to measure surface defects that have been characterized to some level of surface roughness. The surface defects data have learned using artificial neural networks to give a decision in order to move the actuator of arm robot. Force and rotation time have chosen as output parameters of artificial neural networks. Results shows that although there is a considerable change in both parameter values acquired from vision data compared to real data, it is still possible to obtain surface defects characterization using vision sensor to a certain limit of accuracy. The overall results of this research would encourage further developments in this area to achieve robust computer vision based surface measurement systems for industrial robotic, especially in polishing process. Keywords: polishing robot, vision sensor, surface defects, and artificial neural networks

    With increased international competitiveness in the automotive industry, came the concern of the companies save costs and lower production costs. For this purpose many ways are designed to reduce costs and waste of raw materials and reduce activities that do not aggregate value to manufacturing processes. In the early XVII appears the manufacturing system, which processes were hard with little concern for the health and safety of employees and conditions of the workplace. After the advent of the production system called lean manufacturing, a new paradigm in terms of production system capable of providing high levels of productivity and quality. It is based on waste elimination that occur during the production process. After began a new way of thinking, creating a culture of continuous improvement and lean process with no waste and reducing costs, without neglecting the welfare worker and improving the conditions of their work environment. This paper presents a reflection on the application of ergonomics in a lean production system of an automotive industry, using methodology based on the Kaizen (Continuous Improvement) to gain performance and improving the conditions of the workplace, also will be presented with positive and negative points in using this methodology in relation to ergonomics. The research will be conducted by collecting data 'in loco' and interviews with workers. Some studies show that in companies that are lean system and using the methodology of Kaizen, the results of product quality, levels of absenteeism and accidents are better than those obtained in companies that do not apply the same concept.

    The composites appear as an extremely favorable alternative for different industries, due to the fact that it combines the best mechanical properties with the best physic-chemical properties of two or more materials. Nowadays, in the evaluation of materials, besides criteria such as economic viability and performance, the environmental criterion was included in this evaluation. Part of the environmental criteria is the use of biodegradable materials and/or recycled materials. In this sense, researches focused on vegetal fibers, as reinforcement in composites are growing considerably and positive results for its performance were achieved. Moreover, the environmental-friendly approach not only is the unique advantage on usage of vegetal fibers, but also it has an economical advantage, because of the low cost and good performance due to low density. The fiber extracted from the pineapple leaf (PALF) is a new alternative for automotive industry as cellulose-based fiber composite. In this sense, the present paper aims to present the characterization of the pineapple leaf fiber for manufacturing the automotive composite materials. Milled pineapple fibers extracted, in two different ways and submitted to mercerisation treatments, were characterized by mechanical and thermal properties; density; morphology; FTIR spectroscopy, EDX and X-ray diffraction. It is important to characterize the fibers, in order to obtain appropriate mechanical properties of composite. (author)

    Full Text Available Supplier development programs support the development of a supplier's capabilities, usually with the assistance of a buyer. In an industrial environment that lacks home- grown technology, it is of interest to explore precisely how suppliers learn and increase their capabilities. There are also questions regarding how the buyer impacts this learning process, specifically with respect to dependent suppliers for which major buyers account for more than 20% of sales. It is claimed that support from buyers for supplier training has been deficient. Thus, there is a need to identify the types of training that suppliers themselves prefer. The objective of this study is therefore to examine the patterns of learning for dependent suppliers in the Malaysian automotive industry by exploring how suppliers learn best and defining the role of buyers in providing assistance. This study presents a model based on empirical findings and discusses the implications of the findings.

    Full Text Available This paper provides a general overview of the performance indicators used by Brazilian Automotive Industry in its profit sharing agreements, named PLR agreements. The 39 PLR agreements analyzed had their performance indicators classified in six groups: financial, quality, flexibility, productivity, customers and human resources. The results show a massive presence of traditional non-financial indicators, whereas performance indicators to cover social-environmental aspects have not been found. The predominance of indicators related to productivity and quality raised the possibility that in economic cycles with industry activity expansion, the non-financial indicators can be used as proxies of financial indicators. After analyzing the results, it was suggested that, in future, the study of the indicators basket should include its relations with strategic position, technological sophistication and other factors that impact the selection of indicators.

    Full Text Available Abstract Background Musculoskeletal disorders (MSDs due to repetitive work are common in manufacturing industries, such as the automotive industry. However, it's still unclear which MSDs of the upper limb are to be expected in the automotive industry in a first aid unit as well as in occupational precaution examinations. It is also unclear which examination method could be performed effectively for practical reasons and under rehabilitation aspects. Additionally, it was to discuss whether the conception of unspecific description for MSDs has advantages or disadvantages in contrast to a precise medical diagnosis. Methods We investigated the health status of two study populations working at two automotive plants in Germany. The first part included 67 consecutive patients who were seen for acute or chronic MSDs at the forearm over a 4-month period at the plants' medical services. Information about patients' working conditions and musculoskeletal symptoms was obtained during a standardized interview, which was followed by a standardized orthopedic-chiropractic physical examination. In the second part, 209 workers with daily exposure to video display terminals (VDT completed a standardized questionnaire and were examined with function-oriented muscular tests on the occasion of their routine occupational precaution medical check-up. Results The majority of the 67 patients seen by the company's medical services were blue-collar works from the assembly lines and trainees rather than white-collar workers from offices. Rates of musculoskeletal complaints were disproportionately higher among experienced people performing new tasks and younger trainees. The most common MSD in this group were disorders of flexor tendons of the forearm. By contrast, among the 209 employees working at VDT disorders of the neck and shoulders were more common than discomfort in the forearm.

    2007-05-01

    This study is addressed to obtain a design methodology for integrated security sub-modules (constituting the suspension and steering modules) in the car manufacturing industry. The sub-modules are made up of a steel structure and anchorage elements (rubber-metal or plastic-metal), which undergo separate surface treatments to prevent corrosion. Afterwards, the elements are traditionally joined by means of adhesives and screws. This process involves a great number of stages, low quality union methods and generation of corrosion areas that shorten its useful life. This methodology provides automotive suppliers an additional added value and cost reduction, allowing them to increase its competitiveness in a sector that faces the transition from the traditional supply chain to a strategic value chain.

    Full Text Available Capacity waste management is highly essential because under utilization of capacity is often referred to as a major reason for lower productivity among industries around the world. For better estimation of capacity and its utilization and then for its improved management; newer techniques are being devised in industrial sector. The current case of capacity waste problem has been taken up as a Six Sigma project, where we try to analyze critical factors responsible for the capacity waste. Decisions on critical factor selection in analysis phase of Six Sigma are always very crucial. The paper discusses an approach for selection of capacity waste factors at an automotive industry using fuzzy logic based AHP method. The fuzzy AHP is a well recognized tool to undertake the fuzziness of the data involved in choosing the preferences of the different decision variables engaged in the process of capacity waste factors selection. In this context, we have explored six crucial parameters for selection of capacity waste factors. Final ranking is calculated through priority vector thus obtained and it is seen that conveyor malfunction is found to be the key factor for capacity waste among all alternatives at the selected site.

    There are least two general roles that an industrial physicist may be expected to play in the automotive industry. One is the role of technical specialist and the other is the role of general problem solver. A technical specialist must be the Company's resource for a specific set of technical skills. In this case it is important that physics education provide the right skills - ones that are currently critical and will remain critical to the Company's business. In the role of general problem solver, an industrial physicist must provide a broad technical knowledge base that is interdisciplinary in nature as well as the right problem solving skills and an ability to self-teach and learn quickly. Communication skills are a necessary part of each role. A physics education can prepare a student well for either of these roles, but there is room for improvement. In this presentation, I will discuss my experiences and anecdote base, focusing on which aspects of my education I found to be particularly useful and what other educational experiences would have been helpful.

    Full Text Available As a manufacturing, logistics and supply chain hub within ASEAN (Association of Southeast Asian Nations, Thailand holds the 12th spot in global vehicle production for an estimated 2,355 Thai and multinational automotive industry enterprises. Within the Association of Southeast Asian Nations, Thailand ranks number one in automotive production contributing $US11.4 billion to the Thai economy and 12 percent to Thailand’s GDP (Gross Domestic Product, with the automotive industry being Thailand’s leading export sector. However, the automotive companies envisage the difficulty of cultural diversity to manage and coordinate. Therefore, cultural values from the milieu are inducted into the workplace and have a strong impact on both individual behavior and organizational effectiveness and must be direction at all levels for cross-cultural, organizational effectiveness to be achieved. It also became evident that natural disasters are frequent and highly disruptive to the global automotive supply chain and paces must be taken to countervailing the notable and continuing loss to economic growth and organizational effectiveness to both sector units and the global industry. The implementation of strategically placed, environmentally ‘habituated’, automotive parts logistics cache might be one solution to the problem. Given the crucial importance of this sector to the economy of the region and the global supply chain, the researchers surveyed 220 managers using a 7-point Likert scale questionnaire within the multinational industrial clusters of Thailand’s ‘Detroit of Asia’ Eastern Seaboard region. Using Structural Equation Modelling to test the 11 variables on Logistics Management, Supply Chain Management and Organizational Effectiveness in a cross-cultural context, it was determined that collaboration within the supply chain and the exchange of information can reduce uncertainty, with trust being a key ingredient to a JV’s success

    Recycling companies play a leading role in the system of end-of-life vehicles (ELVs) in China. Automotive manufacturers in China are rarely involved in recycling ELVs, and they seldom provide dismantling information for recycling companies. In addition, no professional shredding plant is available. The used automotive electronic control components recycling industry in China has yet to take shape because of the lack of supporting technology and profitable models. Given the rapid growth of the vehicle population and electronic control units in automotives in China, the used automotive electronic control components recycling industry requires immediate development. This paper analyses the current recycling system of ELVs in China and introduces the automotive product recycling technology roadmap as well as the recycling industry development goals. The strengths, weaknesses, opportunities and challenges of the current used automotive electronic control components recycling industry in China are analysed comprehensively based on the 'strengths, weaknesses, opportunities and threats' (SWOT) method. The results of the analysis indicate that this recycling industry responds well to all the factors and has good opportunities for development. Based on the analysis, new development strategies for the used automotive electronic control components recycling industry in accordance with the actual conditions of China are presented.

    Currently there are many automotive companies still unable to effectively prevent consequences of poor ergonomics in their manufacturing processes. This study purpose is to determine the surrounding factors that influence low ergonomics risk awareness among staffs at early product development phase in Malaysia automotive industry. In this study there are four variables, low ergonomic risk awareness, inappropriate method and tools, tight development schedule and lack of management support. The survey data were gathered from 245 respondents of local automotive companies in Malaysia. The data was analysed through multiple regression and moderated regression using the IBM SPSS software. Study results revealed that low ergonomic risk awareness has influenced by inappropriate method and tool, and tight development schedule. There were positive linear relationships between low ergonomic risk awareness and inappropriate method and tools, and tight development schedule. The more inappropriate method and tools applied; the lower their ergonomic risk awareness. The more tight development schedule is the lower ergonomic risk awareness. The relationship between low ergonomic risk awareness and inappropriate method and tools depends on staff's age, and education level. Furthermore the relationship between low ergonomic risk awareness and tight development schedule depends on staff's working experience and number of project involvement. The main contribution of this paper was identified the number of factors of low ergonomics risk awareness and offers better understanding on ergonomics among researchers and automotive manufacturer's employees during product development process.

    Sebastjan Škerlič

    2016-06-01

    Full Text Available Participating in the automotive industry brings new responsibilities for suppliers who, in order to meet customer demands, must strive towards improving business processes, while at the same time reducing costs. These demands can disrupt the operations of companies that do not have a system for controlling logistics costs. On the other hand, customer demands can be the cause of other types of disruptions in companies that have such a system in place, stemming from an excessive focus on cost reduction. To tackle this problem, a survey was conducted on a sample of 30 Slovenian companies that operate as suppliers in the automotive industry. Its objective was to determine how different customer demands along the supply chain can affect the business processes of suppliers and the level of logistics costs. The survey revealed that companies that use a system for controlling logistics costs experience fewer disruptions in their business processes in their efforts to satisfy customer demands. These companies also display a higher level of integration of business processes and use a different approach when dealing with the various participants of the supply chain. The survey also sets clear participation guidelines for suppliers in the supply chain of the automotive industry and points out how companies can benefit from using a system for controlling logistics costs in other ways, aside from the cost controlling aspect.

    CAR undertook this investigation to better understand the costs and challenges of a local (state) regulation necessitating the implementation of alternative or advanced powertrain technology. CAR will attempt to add insight into the challenges that local regulations present to the automotive industry, and to contribute further to the discussion of how advanced powertrain technology may be used to meet such regulation. Any local law that (directly or indirectly) affects light duty motor vehicle fuel economy creates what in effect is a specialty market for powertrain technology. As such these small markets present significant challenges for automotive manufacturers. First, a small market with unique standards presents significant challenges to an industry that has sustained growth by relying on large volumes to achieve scale economies and deliver products at a cost acceptable to the consumer. Further, the challenges of the additional technology make it likely that any powertrain capable of meeting the stringent emissions standards will include costly additional components, and thus will be more costly to manufacture. It is likely that manufacturers would consider the following actions as steps to deliver products to meet the pending California regulatory requirements anticipated as a result of prior California legislation: (1) Substituting more fuel efficient vehicles: Bring in more efficient vehicles from global operations, while likely dropping existing domestic products. (2) Substituting powertrains: Add existing downsized engines (i.e. turbocharged versions, etc.) into California market-bound vehicles. (3) Powertrain enhancements: Add technology to current engine and transmission offerings to improve efficiency and reduce emissions. (4) Incorporating alternative powertrains into existing vehicle platforms: Develop a hybrid or other type of powertrain for an existing vehicle. (5) New powertrains and new platforms: Develop vehicles specifically intended to

    The objective of this study was to quantify the effectiveness of different pretreated iron byproducts from the automotive industry to degrade DDT [(1,1,1-trichloro-2,2-bis(4-chlorophenyl) ethane] in aqueous solutions and soil slurry. Iron byproducts from automotive manufacturing were pretreated by three different methods (heating, solvent and 0.5N HCl acid washing) prior to experimentation. All pretreated irons were used at 5% (wt v-1) to treat 0.014 mM (5 mgL-1) of DDT in aqueous solution. Among the pretreated irons, acid pretreated iron results in the fastest destruction rates, with a pseudo first-order degradation rate of 0.364 d-1. By lowering the pH of the DDT aqueous solution from 9 to 3, destruction kinetic rates increase more than 20%. In addition, when DDT-contaminated soil slurry (3.54 mg kg-1) was incubated with 5% (wt v-1) acid-pretreated iron, more than 90% destruction of DDT was observed within 8 weeks. Moreover, DDT destruction kinetics were enhanced when Fe(II), Fe(III) or Al(III) sulfate salts were added to the soil slurry, with the following order of destruction kinetics: Al(III) sulfate > Fe(III) sulfate > Fe(II) sulfate. These results provide proof-of concept that inexpensive iron byproducts of the automotive industry can be used to remediate DDT-contaminated water and soil.

    Magnesium alloys show a very high potential in automotive applications as constructive metal, whereas the main focus lies on die cast parts. Electronic industry is the major commercial consumer for die castings besides the automobile industry. Room temperature applications like steering wheels and frame components in cars as well as mobile phone- or notebook housings are well established. These castings are produced with AZ- or AM-magnesium alloys, which show good room temperature properties and a good castability. The great alloy development challenge in extending the use of magnesium cast alloys are application for higher temperatures. The application in powertrain components is considered to be the benchmark here. Besides alloy development there are also further research activities in development of casting processes. Semi-solid processes like New-Rheocasting (NRC), Thoxomolding trademark or Thixocasting (TC) are adapted to the requirements of newly developed alloys. Not only cast alloys but also magnesium wrought alloys have moved to the centre of interest in the last decade. Alloy development for improving the formability on the one hand as well as process development in extrusion or rolling has to be done in order to find optimum parameters for deforming magnesium alloys properly.

    Full Text Available Background: The significant economic importance of the country’s automotive industry provided the context for this study. The success of the industry relies on the effectiveness and efficiency of the supply chain, which can be significantly affected by the strength of the supply chain relationships. The role of trust and information sharing in relation to two key theories was considered, namely: organisational information processing theory and game theory. Previous studies have recognised the importance of trust and information sharing in supply chain relationships and considered the effect of trust on information sharing, or the effect of information sharing on trust in a single direction. Thus, the potential cyclical relationship between the two factors has been largely ignored.Objectives: This paper explored the relationship between trust and information sharing in South African automotive supply chains, and establishes the importance of nurturing a cyclical relationship between these two factors. In addition, the role of information technology (IT in supporting this relationship was considered. By improving both trust and information sharing, the performance and competitiveness of the supply chain can be improved.Method: An examination of the effects of a lack of trust in a supply chain relationship, and the consequential lack of information flow, was conducted by means of a case study of an Eastern Cape-based automotive supplier. A case study research method was followed for this study, which made use of multiple data collection methods, including document survey and participant observations. The case selected is an East London based subsidiary of a larger multinational automotive component supplier to both local and international automotive original equipment manufacturers.Results: The findings led to the conclusion that the way forward for competitive supply chains is to build trust in the supply chain in order to improve information

    CAR undertook this investigation to better understand the costs and challenges of a local (state) regulation necessitating the implementation of alternative or advanced powertrain technology. CAR will attempt to add insight into the challenges that local regulations present to the automotive industry, and to contribute further to the discussion of how advanced powertrain technology may be used to meet such regulation. Any local law that (directly or indirectly) affects light duty motor vehicle fuel economy creates what in effect is a specialty market for powertrain technology. As such these small markets present significant challenges for automotive manufacturers. First, a small market with unique standards presents significant challenges to an industry that has sustained growth by relying on large volumes to achieve scale economies and deliver products at a cost acceptable to the consumer. Further, the challenges of the additional technology make it likely that any powertrain capable of meeting the stringent emissions standards will include costly additional components, and thus will be more costly to manufacture. It is likely that manufacturers would consider the following actions as steps to deliver products to meet the pending California regulatory requirements anticipated as a result of prior California legislation: (1) Substituting more fuel efficient vehicles: Bring in more efficient vehicles from global operations, while likely dropping existing domestic products. (2) Substituting powertrains: Add existing downsized engines (i.e. turbocharged versions, etc.) into California market-bound vehicles. (3) Powertrain enhancements: Add technology to current engine and transmission offerings to improve efficiency and reduce emissions. (4) Incorporating alternative powertrains into existing vehicle platforms: Develop a hybrid or other type of powertrain for an existing vehicle. (5) New powertrains and new platforms: Develop vehicles specifically intended to

    ENGLISH ABSTRACT: The South African automotive industry faces increasing challenges for Original Equipment Manufacturers (OEMs and their suppliers to produce high-quality products at low costs. Items purchased by OEMs from the supply chain typically account for more than seventy percent of the total costs of manufactured automobiles. The strategic significance of the purchasing function is subsequently recognised as a major determinant of competitiveness. From a review of literature, a conceptual model is introduced whereby localisation strategies of OEMs, with respect to their main suppliers, can be optimised for competitive advantage. The findings of a case study of a South African OEM’s localisation strategies are presented. Based on the findings, an improved model is proposed that could be used as a guideline to orientate procurement strategies for optimal performance, so as to guarantee the competitive advantage of local OEMs. It is anticipated that these results will provide a platform of effective strategy development for the South African OEMs.

    The automotive repair and refinishing industry has been studied intensively in industrialized countries, in part due to use of hazardous chemicals such as isocyanates and solvents, but little is known about industry practices in the developing world. The main objective of this paper was to investigate environmental and occupational work practices of this industry in a developing region, Sonora, Mexico. An integrated survey approach maximizes the opportunity for identifying risks as well as reducing risks. This investigation included detailed workplace visits to 41 body shops and 6 paint suppliers, as well as a survey of shop owners and 24 workers. Information was collected on work practices, level of technology in the shops, use of personal protective equipment, consumption and handling of hazardous chemicals and waste, hazard communication, and environmental consciousness. Most shops had little capital, outdated technology for exposure control, poor working conditions, high potential for exposure to hazardous chemicals, and little awareness of environmental and occupational health and safety. We concluded that work practices in the Sonoran auto refinishing industry are unsustainable and may pose a health risk to workers and the environment.

    Colour-difference formulas are tools employed in colour industries for objective pass/fail decisions of manufactured products. These objective decisions are based on instrumental colour measurements which must reliably predict the subjective colour-difference evaluations performed by observers' panels. In a previous paper we have tested the performance of different colour-difference formulas using the datasets employed at the development of the last CIErecommended colour-difference formula CIEDE2000, and we found that the AUDI2000 colour-difference formula for solid (homogeneous) colours performed reasonably well, despite the colour pairs in these datasets were not similar to those typically employed in the automotive industry (CIE Publication x038:2013, 465-469). Here we have tested again AUDI2000 together with 11 advanced colour-difference formulas (CIELUV, CIELAB, CMC, BFD, CIE94, CIEDE2000, CAM02-UCS, CAM02-SCD, DIN99d, DIN99b, OSA-GP-Euclidean) for three visual datasets we may consider particularly useful to the automotive industry because of different reasons: 1) 828 metallic colour pairs used to develop the highly reliable RIT-DuPont dataset (Color Res. Appl. 35, 274-283, 2010); 2) printed samples conforming 893 colour pairs with threshold colour differences (J. Opt. Soc. Am. A 29, 883-891, 2012); 3) 150 colour pairs in a tolerance dataset proposed by AUDI. To measure the relative merits of the different tested colour-difference formulas, we employed the STRESS index (J. Opt. Soc. Am. A 24, 1823-1829, 2007), assuming a 95% confidence level. For datasets 1) and 2), AUDI2000 was in the group of the best colour-difference formulas with no significant differences with respect to CIE94, CIEDE2000, CAM02-UCS, DIN99b and DIN99d formulas. For dataset 3) AUDI2000 provided the best results, being statistically significantly better than all other tested colour-difference formulas.

    The infatuation for diesel vehicles in Europe has led to an unexpected growth of this market. The reason is linked with the improvements made in diesel engine technology and with the rise of automotive fuel prices. Car and vehicle equipment manufacturers and sub-contractors have to increase their production and manpower and to adopt new work schedules for a better exploitation of factories capacity. However, the development of the direct injection (common-rail) technology for diesel engines requires complex and precise machining procedures that are hardly compatible with an enhanced mass production.

    A significant number of German companies are installed in Brazil, many of them in the automotive or automotive supplier sectors. Information about the economic, environmental and social performance of major companies in these sectors is easily obtainable from sustainability reports, available as printed reports distributed by the head offices or as files for downloading in corporate websites. This paper gives a brief review about corporate sustainability and the results of a study carried out on sustainability reports of three companies with head offices (or, in one case, a relatively independent subsidiary) in Germany and subsidiaries in Brazil. The results show that, although the sustainability reports of the analyzed companies contain relevant information, they do not allow any sustainability benchmarking that could distinguish better and worse environmental and social performances. They also do not help an environmental and social performance comparison between plants in the European Union (e.g. Germany) and Mercosur (e.g. Brazil). Nevertheless, they give some evidence of efforts aligned with the principles of the Global Compact.

    Salihoglu, Guray; Salihoglu, Nezih Kamil

    2016-03-15

    The automotive manufacturing process results in the consumption of several natural sources and the generation of various types of wastes. The primary source of hazardous wastes at an automotive manufacturing plant is the painting process, and the major waste fraction is paint sludge, which is classified with EU waste code of 080113* implying hazardous characteristics. The amount of the paint sludge generated increases every year with the worldwide increase in the car production. The characteristics of the paint sludge, which mainly designate the management route, are mainly determined by the type of the paint used, application technique employed, and the chemicals applied such as flocculants, detackifiers, pH boosters, antifoam agents, and biocides as well as the dewatering techniques preferred. Major routes for the disposal of the paint sludges are incineration as hazardous waste or combustion at cement kilns. Because of high dissolved organic carbon content of the paint, the paint sludge cannot be accepted by landfills according to European Union Legislations. More investigations are needed in the field of paint sludge recycling such as recycling it as a new paint or as other formulations, or making use of the sludge for the production of construction materials. Research on the applicability of the paint sludge in composting and biogasification can also be useful. Ongoing research is currently being conducted on new application techniques to increase the effectiveness of paint transfer, which helps to prevent the generation of paint sludge. Advancements in paint and coating chemistry such as the reduction in the coating layers with its thickness also help to decrease the level of paint sludge generation. Investigations on the effects of the chemicals on the recycling potential of paint sludges and consideration of these effects by the chemical manufacturer companies would be extremely important. This review presents the formation of paint sludge, the factors

    2011-06-01

    Fuel cells (FCs) are considered essential future energy technologies by developed and developing economies alike. Several countries, including the United States, Japan, Germany, and South Korea have established publicly funded R&D and market transformation programs to develop viable domestic FC industries for both automotive and non-automotive applications. Important non-automotive applications include large scale and small scale distributed combined heat and electrical power, backup and uninterruptible power, material handling and auxiliary power units. The U.S. FC industry is in the early stages of development, and is working to establish sustainable markets in all these areas. To be successful, manufacturers must reduce costs, improve performance, and overcome market barriers to new technologies. U.S. policies are assisting via research and development, tax credits and government-only and government-assisted procurements. Over the past three years, the industry has made remarkable progress, bringing both stack and system costs down by more than a factor of two while improving durability and efficiency, thanks in part to government support. Today, FCs are still not yet able to compete in these markets without continued policy support. However, continuation or enhancement of current policies, such as the investment tax credit and government procurements, together with continued progress by the industry, appears likely to establish a viable domestic industry within the next decade.

    2016-08-01

    Full Text Available The exhaust system plays a vital role in removing the gaseous emissions that is being produced within the combustion chamber during fuel-air mixture activities. The exhaust system is defined as a series of chambers and pipes that starts at the engine and ends at the back of the car with the tail pipe. However if there are any leaks in the exhaust system, it provide a direct path for the emission gaseous including carbon monoxide to enter can be very dangerous as it provides a direct path for carbon monoxide and other dangerous gaseous emissions to enter the cowl vent at the base of the windshield and directly to the passenger compartment. The risk of exposure to these hazardous gaseous is also high especially during vehicle maintenance services in suspected cases of leakages to the exhaust system.  The inspection of the exhaust system is done manually in most of the automotive services workshops. In this paper, accidental risks of performing these inspection jobs on a vehicle’s exhaust system, performed by a technician are discussed. In order to minimize the risks to technicians or mechanics, a prototype device to detect exhaust leakage was developed using a gas sensor module and a web camera. This device was successfully operated in detecting possible leakages of the exhaust system.

    While you refuel for gas, why not refuel for information or download vehicle data? This paper analyzes in extensive detail the user segmentation by vehicle usage, service offering, and full business models from WLAN (Wireless Local Area Network) hot spot services delivered to vehicles (private, professional, public) around gas stations. Also analyzed are the parties which play a role in such service authorization, provisioning and delivery, with all the dependencies modelled by attributed digraphs. Service planning is included as to WLAN base station capabilities. Five year financial models (CAPEX,OPEX), and data pertain to two possible service suppliers: multi-service oil companies, and mobile service operators (or MVNO). Model optimization on the return-on-investment (ROI) is carried out for different deployment scenarios, geographical coverage assumptions, as well as tariff structures. Comparison is also being made with public GPRS data services, as precursors for 3G services, and the effect of WLAN roaming is analyzed. Analysis shows that due to manpower costs and marketing costs, suitable ROI will not be achieved unless externalities are accounted for and innovative tariff structures are introduced. Open issues and further research are outlined. Further work is carried out, also with automotive electronics sector, wireless systems providers, wireless terminals platform suppliers, and vehicle manufacturers.

    The evaluation of genome integrity in populations occupationally exposed to combine industrial factors is of medical importance. In the present study, the DNA-damage response was estimated by means of the alkaline comet assay in a sizeable cohort of volunteers recruited among workers in the automotive industry. For this purpose, freshly collected lymphocytes were treated with hydrogen peroxide (100μM, 1min, 4°C) in vitro, and the levels of basal and H(2)O(2)-induced DNA damage, and the kinetics and efficiency of DNA repair were measured during a 180-min interval after exposure. The parameters studied in the total cohort of workers were in a range of values prescribed for healthy adult residents of Belarus. Based on the 95th percentiles, individuals possessing enhanced cellular sensitivity to DNA damage were present in different groups, but the frequency was significantly higher among elderly persons and among individuals with chronic inflammatory diseases. The results indicate that the inter-individual variations in DNA-damage response should be taken into account to estimate adequately the environmental genotoxic effects and to identify individuals with an enhanced DNA-damage response due to the influence of some external factors or intrinsic properties of the organism. Underling mechanisms need to be further explored.

    2012-06-01

    Full Text Available The production of fiberglass reinforced plastic composite parts may cause serious damages to the health of workers and/or the environment, especially due to the generation of process trimmings, noise level and gas emission.  In view of that, this essay aims at assessing the main impacts of the Molding and Finish processes of an automotive plant on the environment and occupational health. It was observed that the open molding method adopted by the studied plant is the main cause of the generation of residues and that the waste of raw materials as trimmings may reach up to 30%. The final destination of those trimmings, which represent 45% of all the residues generated by the factory, is the industrial landfill. It was also observed that, due to the use of open molds, the levels of styrene and fiber dust were above the tolerance limits, presenting risks to the health of the workers.  Therefore, the studied company should consider the possibility of adopting less aggressive technologies, such as that used in closed molds. The reduction of the negative impacts of the productive processes in their source should be part of the company’s policy. Furthermore, the prevention must be continuous and improved every day.

    Science.gov (United States)

    Mittelstädt, C.; Seefeld, T.; Reitemeyer, D.; Vollertsen, F.

    This work shows the potential of two-beam laser brazing for joining both Zn-coated steel and 22MnB5. Brazing of Zn-coated steel sheets using Cu-Si filler wire is already state of the art in car manufacturing. New press-hardened steels like 22MnB5 are more and more used in automotive industry, offering high potential to save costs and improve structural properties (reduced weight / higher stiffness). However, for joining of these ultra-high strength steels investigations are mandatory. In this paper, a novel approach using a two-beam laser brazing process and Cu-base filler material is presented. The use of Cu-base filler material leads to a reduced heat input, compared to currently applied welding processes, which may result in benefits concerning distortion, post processing and tensile strength of the joint. Reliable processing at desired high speeds is attained by means of laser-preheating. High feed rates prevent significant diffusion of copper into the base material.

The sampling and sample preparation procedures were based on methods established by the Company of Sanitation and Technology (CETESB L9.234) and also by the Environmental Protection Agency (EPA - Method 29). The analysis was performed at XRF Beamline (D09B-XRF) in the Synchrotron Light Source Laboratory (Campinas/SP). A white beam of synchrotron radiation was used for sample and standard excitation which were irradiated by 100 seconds. For X-ray lines detection, a Ge (HP) detector with 150 eV of resolution at 5.9 keV was employed. For zinc, iron, barium, calcium and potassium, the values obtained were in the range of 30 mg/Nm{sup 3} and, for other elements, the concentrations were approximately 1 mg/Nm{sup 3}. The sum of As, Be, Co, Cr, Cu, Mn, Ni, Pb, Sb, Se, Sn, Te and Zn concentration was compared with the limits established by CONAMA 264/1999 and SEMA 041/2002 resolutions (7.0 mg/Nm{sup 3}) and it was observed that, for all samples, sums are higher than the permissive value mainly due to the high concentration of zinc. Detection limits for SR-TXRF technique were 0.10 mug/Nm{sup 3} for Pb and 0.02 mug/Nm{sup 3} for Zn. (author)

    Polymeric nanocomposites are novel materials of huge interest owing to their favourable cost/performance ratio with low amount of nanofillers, improved thermal resistance, flame retardancy and mechanical properties in relation to their matrices. In this work, composites based on post-industrial waste or primary recycled poly(butylene terephthalate) and 5 wt.% of organic modified montmorillonite clays were melt compounded using a twin-screw extruder. A 2(2) factorial experimental design was used to study the compounding and processing variables: Organic modified montmorillonite with one or two hydrogenated tallow (initial basal spacing) and screw speed of the extruder. X-ray diffraction and transmission electron microscopy suggest that a partial exfoliation of the organoclay in the recycled poly(butylene terephthalate) matrix was achieved for organic modified montmorillonite with lower initial basal spacing. On the other hand, formulations containing organic modified montmorillonite with higher initial basal spacing showed only intercalated structure. The recycled poly(butylene terephthalate)-organic modified montmorillonite nanocomposites did not drip flaming material during burning tests. Storage of dynamic-mechanical, tensile and flexural moduli of the recycled poly(butylene terephthalate)-organic modified montmorillonite were improved when compared with both virgin and recycled poly(butylene terephthalate)s, mainly for nanocomposites formulated at a lower initial basal spacing organoclay. This could be related to a better diffusion of polymer into organic modified montmorillonite layers compared with the higher initial basal spacing organoclay. The improvements on the physical properties of recycled poly(butylene terephthalate) showed the feasibility to add value to primary recycled engineering thermoplastics with a very small amount of organic modified montmorillonite.

Dentre as peças automotivas, os pára-choques são relativamente fáceis de serem reciclados devido às suas dimensões e por constituírem, geralmente, de um único material, o polipropileno (PP. Neste trabalho, analisaram-se as propriedades mecânicas de misturas de PP virgem e reciclado, em três porcentagens diferentes, a fim de detectar as alterações das mesmas, relacionando-as à qualidade do produto. Concluiu-se que porcentagens de reciclado acima de 30% causam deterioração das propriedades mecânicas do produto. Este estudo visa a fornecer uma contribuição para o aumento na utilização de plásticos reciclados na indústria automotiva.The automotive industry is now responsible for a large share of plastic consumption, which prompted increasing investments in recycling processes, also due to the need of ambient protection. Among the automotives parts, bumpers are relatively easy to be recycled due to their dimensions and because they are made of a single material, polypropylene (PP. In this work, the mechanical properties of mixtures of virgin and recycled PP, in three different percentages, were analyzed in order to detect alterations and associate them with the product quality. It was concluded that percentages of recycled material above 30% deteriorate the mechanical properties of the product. This study aims to provide a contribution to the increase in the recycled plastic use in the automotive industry.

    Full Text Available Present design trends in automotive manufacture have shifted emphasis to alternative lightweight materials in order to achieve higher fuel efficiency and to bring down vehicle emission. Although some other joining techniques are more and more being used, spot welding still remains the primary joining method in automobile manufacturing so far. Spot welds for automotive applications should have a sufficiently large diameter, so that nugget pullout mode is the dominant failure mode. Interfacial mode is unacceptable due to its low load carrying and energy absorption capability. Strength tests with different static loading were performed in, to reveal the failure mechanisms for the lap-shear geometry and the cross-tension geometry. Based on the literature survey performed, venture into this work was amply motivated by the fact that a little research work has been conducted to joining of dissimilar materials like non ferrous to ferrous. Most of the research works concentrated on joining of different materials like steel to steel or aluminium alloy to aluminium alloy by resistance spot welding. In this work, an experimental study on the resistance spot weldability of aluminium alloy (Al 6063 and austenitic stainless steel (AISI304 sheets, which are lap joined by using a pedestal type resistance spot welding machine. Welding was conducted using a 45-deg truncated cone copper electrode with 10-mm face diameter. The weld nugget diameter, force estimation under lap shear test and T – peel test were investigated using digital type tensometer attached with capacitive displacement transducer (Mikrotech, Bangalore, Model: METM2000ER1. The results shows that joining of Al 6063 and AISI 304 thin sheets by RSW method are feasible for automotive structural joints where the loads are below 1000N act on them, it is observed that by increasing the spots per unit length, then the joint with standing strength to oppose failure is also increased linearly incase of

    The purpose of this paper is to analyze different power devices - emitters of optical flow, from the point of view of optical coupling, emitted optical powers, optical fiber losses and receiver. The research and characterization of the transmission through a power optical system is done using a computer system specialized for the automotive industry. This system/platform can deliver current pulses that are controlled by a computer through a software (it is possible to set different parameters such as pulse repetition frequency, duty cycle, and current intensity). For the experiments a power Fabry Perot 1035 laser diode operating in pulse with μφ 1055 nm, Ith = 40 mA, and Iop =750 mA was used with a single-mode SFM 128 optical fiber and an EM type optical coupler connected through alignment. Two types of measurements were conducted to demonstrate the usefulness of the experimental structure. In the first case the amplitude of the voltage pulses was measured at the output of an optical detector with receiving diode in a built-in amplifier with a 50 kΩ load resistance. In the second stage measurements were conducted to determine the optical power injected in the optical fiber and received at the reception cell of a power meter. Another parameter of optical coupling that can be measured using the experimental structure is irradiation. This parameter is very important to determine the optimum cutting angle of the fiber for continuity welding.

  16. The challenge to the automotive battery industry: the battery has to become an increasingly integrated component within the vehicle electric power system

    Meissner, Eberhard; Richter, Gerolf

    During the time that the automotive battery was considered to be just a passive component in a vehicle electric power system, the battery industry's answer to all new challenges was constructive improvements. The emerging requirements of even higher function reliability cannot, however be met this way. A battery manufacturer of today has to give recommendations for the appropriate choice of the electrical architecture and has to design batteries that suit best the requirements. In addition, manufactures have to be engaged in the technology of battery management, of battery monitoring and state detection, and performance of prediction under future operation conditions. During service on-board a vehicle, battery performance undergoes significant changes, e.g., loss of storage capability, increase in internal resistance, and changes in voltage characteristics. These ageing processes have to be considered when the electrical architecture is being designed and management strategies are being formulated. Battery monitoring and state detection must be able to identify and quantify battery degradation. Moreover, performance prediction as well as management strategies have to be corrected on account of the changing battery characteristics.

    2003-07-15

    The international automotive industry is under pinned by a dual recurrent movement of concentration and internationalization of the production. Its recent scale was the consequence of a set of strategies developed by the major auto-makers to cope with two exogenous phenomenon affecting the automotive industry. On one hand, we are talking about the saturation of the traditional automotive markets (North America, Western Europe and Japan). On the other hand, the increasing severity of the major regulations concerning the industry, notably the ones about environmental protection, is involved. The first part of the dissertation is first devoted to underline these two exogenous phenomenon, then the major strategies adopted by the auto-makers to face them are defined. Finally, the analysis turns on the resulting increase of the concentration and of the internationalization of the production. We focus on this last point and on the problem of international location of industrial activities faced by the auto-makers because of it. The second part is about providing an empirical framework to help solving these problems through parametric stochastic cost production frontiers and cost-efficiency levels. For this purpose, the analytical foundations of both of these notions are introduced, then several empirical estimation methods of a cost frontier are exposed. Finally, these methods are used to treat two real examples illustrating some of the problems about the international location of the productive activities of a major auto-maker. The point for him is to choose the most favorable configuration of its industrial system, by comparing the competing solutions through their respective cost-efficiency levels. The benefit of using additional data analysis methods to draw these comparisons is shown. (author)

    Full Text Available Resistance spot welding is a fabrication process highly used in the structures assembly. This fact evidences the importance of this welding process control, due to its efficiency, productivity speediness and straightforward simple automation. This work aimed to study the weldability of zinc coated and uncoated steel sheets for automotive industry, comparing the performance of two welding equipments with two current outputkinds: alternating current (AC and medium frequency direct current (DC. The welding parameters were kept constant: 260 kgf (force, 150 ms (time and 7.0 kA (welding current, based upon an optimization parameters methodology. The joints were characterized using optical metallography (spot diameter, indentation depth and weld penetration depth, mechanical tensile-shear tests and electrical measurements: contact electrical resistance, dynamic resistance and dynamic energy. The results showed that welding in medium frequency direct current was more efficient in generating heat in zinc coated sheets and uncoated sheets than alternating current equipment. In welding using AC and DC equipments in zinc coated sheets, the spot weld time formation was 25ms longer than uncoated steel sheets spot weld time. The burn of zinc during welding did not damage the spot weld formation with AC or DC equipments. The electrical contact resistance increased with the roughnessand also presented 52% higher in uncoated sheets than in zinc coated sheets. Finally, the increase in dynamicresistance and dynamic energy augmented the spot weld diameter for both welding equipments. As a final conclusion, the medium frequency direct current equipment presented better results than wave alternating current

    Blake, Charles L; Dotson, G Scott; Harbison, Raymond D

    2008-12-01

    Two independent assessments were performed of airborne asbestos concentrations generated during automotive repair work on vintage vehicles . The first involved removal of asbestos-containing seam sealant, and the second involved servicing of a drive clutch. Despite the relatively high concentrations (5.6-28%) of chrysotile fibers detected within bulk samples of seam sealant, the average asbestos concentration for personal breathing zone (PBZ) samples during seam sealant removal was 0.006 f/cc (fibers/cubic centimeter of air). Many other air samples contained asbestos at or below the analytical limit of detection (LOD). Pneumatic chiseling of the sealant material during removal resulted in 69% of area air samples containing asbestos. Use of this impact tool liberated more asbestos than hand scraping. Asbestos fibers were only detected in air samples collected during the installation of a replacement clutch. The highest asbestos corrected airborne fiber concentration observed during clutch installation was 0.0028 f/cc. This value is approximately 100 times lower than Occupational Safety and Health Administration's (OSHA) permissible exposure limit (PEL) of 0.1f/cc. The airborne asbestos concentrations observed during the servicing of vintage vehicles with asbestos-containing seam sealant and clutches are comparable to levels reported for repair work involving brake components and gaskets.

    N. M. Hammad

    2014-06-01

    Full Text Available The estimation of vehicle battery performance is typically addressed by testing the battery under specific operation conditions by using a model to represent the test results. Approaches for representing test results range from simple statistical models to neural networks to complex, physics-based models. Basing the model on test data could be problematical when testing becomes impractical with many years life time tests. So, real time estimation of battery performance, an important problem in automotive applications, falls into this area. In vehicles it is important to know the state of charge of the batteries in order to prevent vehicle stranding and to ensure that the full range of the vehicle operation is exploited. In this paper, several battery models have studied including analytical, electrical circuits, stochastic and electro- chemical models. Valve Regulated Lead Acid “VRLA” battery has been modelled using electric circuit technique. This model is considered in the proposed Battery Monitoring System “BMS”. The proposed BMS includes data acquisition, data analysis and prediction of battery performance under a hypothetical future loads. Based on these criteria, a microprocessor based BMS prototype had been built and tested in automotive Lab,. The tests show promising results that can be used in industrial applications

    2014-06-01

    Full Text Available Fatigue design of automotive axle parts is of prior concern because of these are high safety parts and they are expected to drive the overall vehicle mass reduction. In this framework, the stamping process is widely used to form axle parts, before assembling them by welding. Consequently, the mechanical and physical characteristics of the blank sheet are modified, having a strong influence on the fatigue behavior. In this paper, we address the consequences of the stamped process on the fatigue design and how they may be effectively taken into account in the automotive industry. Actually, the coupling between the stamping process and the fatigue design is under development at PSA Peugeot Citroën Company since several years. Such an analysis deals with some major topics: thickness variation, plastic hardening and deformation, and residual stress. All of these ingredients result in fatigue criteria evolutions: it is important to stress that the stamping process can have advantageous or disadvantageous consequences on the fatigue design. This is here highlighted on some examples, dealing with front and rear axles.

    Textiles are widely used in the automotive industry to provide both comfort to the passengers and an aesthetic appearance to the automotive interior. They can also be used to reduce automotive interior noise, which can make automotive travel safer and more comfortable. Knitted fabrics are used widely in automotive upholstery; however, the sound absorbency of a single layer of a knitted fabric is inadequate for the reduction of automotive interior noise. This paper investigates the sound absorbency of a novel knitted spacer fabric, which can be used in automotive upholstery and has the potential for greater sound absorbency than a conventional plain knitted fabric and its derivatives. The spacer fabric is modelled as a porous sound absorber and its sound absorbency is studied with regard to its structural parameters.

    Arnold, Scot

    1993-01-01

    New technology generally serves two main goals of the automotive industry: one is to enable vehicles to comply with various governmental regulations and the other is to provide a competitive edge in the market. The latter goal can either be served through improved manufacturing and design capabilities, such as computer aided design and computer aided manufacturing, or through improved product performance, such as anti-lock braking (ABS). Although safety features are sometimes customer driven, such as the increasing use of airbags and ABS, most are determined by regulations as outlined by the Federal Motor Vehicle Safety Standards (FMVSS). Other standards, set by the Environmental Protection Agency, determine acceptable levels of emissions and fuel consumption. State governments, such as in California, are also setting precedent standards, such as requiring manufacturers to offer zero-emission vehicles as a certain fraction of their sales in the state. The drive to apply new materials in the automobile stems from the need to reduce weight and improve fuel efficiency. Topics discussed include: new lightweight materials; types of automotive materials; automotive composite applications; the role for composite materials in automotive applications; advantages and disadvantages of composite materials; material substitution economics; economic perspective; production economics; and composite materials production economics.

    2013-02-01

    First book about the aeroacoustics of automotive turbochargers. Author of the book ''Rotordynamics of Automotive Turbochargers'', Springer, 2012. Written by an R and D expert in the turbocharger industry. Aero and Vibroacoustics of Automotive Turbochargers is a topic involving aspects from the working fields of thermodynamics of turbomachinery, aerodynamics, rotordynamics, and noise propagation computation. In this broadly interdisciplinary subject, thermodynamics of turbomachinery is used to design the turbocharger and to determine its operating conditions. Aerodynamics is needed to study the compressor flow dynamics and flow instabilities of rotating stall and surge, which can produce growling and whining-type noises. Rotordynamics is necessary to study rotor unbalance and self-excited oil-whirl instabilities, which lead to whistling and constant tone-type noises in rotating floating oil-film type bearings. For the special case of turbochargers using ball bearings, some high-order harmonic and wear noises also manifest in the rotor operating range. Lastly, noise propagation computation, based on Lighthill's analogy, is required to investigate airborne noises produced by turbochargers in passenger vehicles. The content of this book is intended for advanced undergraduates, graduates in mechanical engineering, research scientists and practicing engineers who want to better understand the interactions between these working fields and the resulting impact on the interesting topic of Aero and Vibroacoustics of Automotive Turbochargers.

    Naskar, Amit K.; Keum, Jong K.; Boeman, Raymond G.

    2016-12-01

    Over the past several decades, the automotive industry has expended significant effort to develop lightweight parts from new easy-to-process polymeric nanocomposites. These materials have been particularly attractive because they can increase fuel efficiency and reduce greenhouse gas emissions. However, attempts to reinforce soft matrices by nanoscale reinforcing agents at commercially deployable scales have been only sporadically successful to date. This situation is due primarily to the lack of fundamental understanding of how multiscale interfacial interactions and the resultant structures affect the properties of polymer nanocomposites. In this Perspective, we critically evaluate the state of the art in the field and propose a possible path that may help to overcome these barriers. Only once we achieve a deeper understanding of the structure-properties relationship of polymer matrix nanocomposites will we be able to develop novel structural nanocomposites with enhanced mechanical properties for automotive applications.

  8. Status and Prospects of the Global Automotive Fuel Cell Industry and Plans for Deployment of Fuel Cell Vehicles and Hydrogen Refueling Infrastructure

    Energy Technology Data Exchange (ETDEWEB)

    Greene, David L [ORNL; Duleep, Gopal [HD Systems

    2013-06-01

    Automobile manufacturers leading the development of mass-market fuel cell vehicles (FCVs) were interviewed in Japan, Korea, Germany and the United States. There is general agreement that the performance of FCVs with respect to durability, cold start, packaging, acceleration, refueling time and range has progressed to the point where vehicles that could be brought to market in 2015 will satisfy customer expectations. However, cost and the lack of refueling infrastructure remain significant barriers. Costs have been dramatically reduced over the past decade, yet are still about twice what appears to be needed for sustainable market success. While all four countries have plans for the early deployment of hydrogen refueling infrastructure, the roles of government, industry and the public in creating a viable hydrogen refueling infrastructure remain unresolved. The existence of an adequate refueling infrastructure and supporting government policies are likely to be the critical factors that determine when and where hydrogen FCVs are brought to market.

    Abstract When the subject rotation between workstations (job rotation) is inside the organizations it's seemed that technically there are lots of restrictions to the development of an adequate system of rotation. We went from the need for an advanced ergonomic study and even possible restrictions of versatility and training of employees. The implementation of the ideal system of rotation passes through stages of development and research ergonomic study of the level of employee versatility, awareness and discussion with employees, implementation of the proposed system, feedback and audits for maintenance of the ideal sequence and time of rotation. For the success of the project there is a need for multidisciplinary involvement in the areas of manufacturing engineering, industrial engineering, human resources, medical services and manufacturing. Rotation between the tasks may mean that a worker should conduct two or more different activities in different parts of the day (ie. change between activity A and activity B "between 1 hours and 2 hours interval). An important consideration is to ensure that different activities do not present the same ergonomic risk for the same body part. The tracing of the execution of the activity is an important factor for production processes. Thus it is possible to conduct appropriate levels of training for employees and ensure safe and sustainable processes in terms of workers' health, productivity and quality.

    Under practical industrial conditions, aged, rather than fresh, catalyst performances is required to meet various regulatory emissions levels. While CeO{sub 2} is recognized as critical in allowing practically aged Pt, Rh catalysts to meet these performance targets, debate continues concerning the physicochemical mechanisms responsible for the performance enhancement. Suppressed precious metal sintering and stabilization of support {gamma}-Al{sub 2}O{sub 3} against surface area loss and structural phase changes are the principle physical mechanisms suggested. Chemical promotion by CeO2 has been attributed to oxygen storage, enhanced water gas shift activity, and enhanced CO oxidation activity through a precious metal-CeO2 coupling mechanisms. The authors have attempted to distinguish the relative contributions of these physical and chemical mechanisms to the performance of practical Pt, Rh catalysts. Two catalysts were aged in tandem using standard dynamometer methods. One was a fully formulated reference catalyst and the other was a CeO{sub 2}-free catalyst. Several potential chemical promotional mechanisms of CO oxidation via a more facile reaction pathway involving coupling between the precious metals and CeO{sub 2}.

    1985-01-01

    The outstanding thermal, physical and chemical properties of ceramic fibres make them a noticeable contender for inclusion in engineered systems to satisfy such performance demands. A wide range of fibres and fibre-based products are available which exhibit such characteristics as high temperature continuous service ability (1600/sup 0/C if required), low thermal conductivity, excellent resistance to chemical attack (including reducing conditions), good acoustic performance at all temperatures and good resistance to vibration. They are also lightweight, fireproof and incombustible. Ceramic fibres should really be referred to as refractory fibres as they are based on combinations of high purity alumina and silica. Two groups of products exist. The most common have a continuous-use temperature of 1260/sup 0/C. These fibres are characterized by an alumina content of 40-50% but refractoriness and temperature use limit can be increased to about 1400/sup 0/C by modifying the basic chemistry. This generally involves increasing the alumina content to as much as 62% or adding chromia or zirconia to the basic mix. The second and less common group of fibres is characterized by both chemistry and crystal morphology. Chemistry is biased towards a high alumina content (over 70%), while production routes are designed to yield as high a crystal phase (and so enhanced high temperature stability) as possible.

    The United States Automotive Materials Partnership LLC (USAMP) was formed in 1993 as a partnership between Chrysler Corporation, Ford Motor Company, and General Motors Corporation. Since then the U.S. Department of Energy (DOE) has supported its activities with funding and technical support. The mission of the USAMP is to conduct vehicle-oriented research and development in materials and materials processing to improve the competitiveness of the U.S. Auto Industry. Its specific goals are: (1) To conduct joint research to further the development of lightweight materials for improved automotive fuel economy; and (2) To work with the Federal government to explore opportunities for cooperative programs with the national laboratories, Federal agencies such as the DOE and universities. As a major component of the DOE's Office of FreedomCAR and Vehicle Technologies Program (FCVT) collaboration with the USAMP, the Automotive Lightweighting Materials (ALM) program focuses on the development and validation of advanced materials and manufacturing technologies to significantly reduce automotive vehicle body and chassis weight without compromising other attributes such as safety, performance, recyclability, and cost. The FCVT was announced in FY 2002 and implemented in FY 2003, as a successor of the Partnership for a New Generation of Vehicles (PNGV), largely addressed under the first Cooperative Agreement. This second USAMP Cooperative Agreement with the DOE has expanded a unique and valuable framework for collaboratively directing industry and government research efforts toward the development of technologies capable of solving important societal problems related to automobile transportation. USAMP efforts are conducted by the domestic automobile manufacturers, in collaboration with materials and manufacturing suppliers, national laboratories, universities, and other technology or trade organizations. These interactions provide a direct route for implementing newly

    Full Text Available In recent years it has been widely discussed the use of continuous improvement in all kind of business and particularly in companies belonging to the automotive industry. Many authors mention improvements, in key indicators of production through the use of continuous improvement tools. At the same time, different authors talk about how to sustain the continuous improvement over time, and try to identify inhibitors and enablers for the sustainability of continuous improvement. But despite this, one can still find first tier suppliers in the automotive industry which have not implemented systems of continuous improvement. This study aims to identify, classify, prioritize and discuss the different enablers and inhibitors which can be found in automotive suppliers companies. For that reason some interviews were conducted with first tier suppliers in the automotive industry that have succeeded or failed in implementing continuous improvement.

    intensa nos relacionamentos mais colaborativos.Much of the literature on performance measurement in industrial companies is based on an internal perspective, i.e., companies are investigated individually. With the emergence of the supply chain management concept, the demand for a review of knowledge and performance measurement systems has increased considering the supply chain as a whole. Thus, the introduction of new productive configurations, such as the industrial condominium, has stimulated the development of new standards of relationship in supply chains introducing new ways to conduct performance management. Therefore, the main objective of the present study was to identify the occurrence and to analyze the key characteristics of performance measurement in a representative supply chain of the Brazilian automotive industry that has an industrial condominium configuration. This study was exploratory in nature, and the data were collected through interviews conducted with executives involved with this topic in these companies using a semi-structured questionnaire. As main result, the occurrence of a single supply chain performance measurement system was not identified in the supply chain studied. In fact, the automaker internal performance measurement system unfolds upstream and downstream affecting the performance measurement systems of the four suppliers and the car dealer studied. Analyzing the performance indicators of these companies, it can be said that the upstream measures are connected to the operational aspects related to quality, production, and delivery performance, while the downstream measures are more strategic and related to marketing. Furthermore, it was also found that the supply chain performance measurement tends to be more intense in collaborative relationships.

    An experiment was performed to determine whether typical industrial automotive color paint comparisons made using real physical samples could also be carried out using a digital simulation displayed on a calibrated color television monitor. A special light booth, designed to facilitate evaluation of the car paint color with reflectance angle, was employed in both the real and virtual color comparisons. Paint samples were measured using a multi-angle spectrophotometer and were simulated using a commercially available software package. Subjects performed the test quicker using the computer graphic simulation, and results indicate that there is only a small difference between the decisions made using the light booth and the computer monitor. This outcome demonstrates the potential of employing simulations to replace some of the time consuming work with real physical samples that still characterizes material appearance work in industry.

    A program to obtain automotive engine performance data for use in estimating vehicle emission and fuel economy in varied service and duty is described. An experimental test procedure for generating fuel consumption and emissions data adequate to characterize an engine over its full operating range was developed for steady-state tests. The development of a test procedure for transient testing is currently under way. The steady-state data will be collected from approximately 23 different engines, including: (1) 16 current production spark-ignition engines; (2) 3 pre-production or prototype advanced design spark-ignition engines; and (3) 4 light-duty diesel engines which are, or could be, used in passenger car applications. To date, steady-state ''engine maps'' were completed on 10 engines. A simplified model used to compare steady-state data with chassis dynamometer data indicates that results thus far can be used to obtain estimates of fuel economy in automobiles.

    The Graduate Automotive Technology Education (GATE) Center at the University of Tennessee, Knoxville has completed its sixth year of operation. During this period the Center has involved thirteen GATE Fellows and ten GATE Research Assistants in preparing them to contribute to advanced automotive technologies in the center's focus area: hybrid drive trains and control systems. Eighteen GATE students have graduated, and three have completed their course work requirements. Nine faculty members from three departments in the College of Engineering have been involved in the GATE Center. In addition to the impact that the Center has had on the students and faculty involved, the presence of the center has led to the acquisition of resources that probably would not have been obtained if the GATE Center had not existed. Significant industry interaction such as internships, equipment donations, and support for GATE students has been realized. The value of the total resources brought to the university (including related research contracts) exceeds $4,000,000. Problem areas are discussed in the hope that future activities may benefit from the operation of the current program.

    Replacement of 50 percent of the liquid fuels used in static industrial applications by solid fuel would reduce the crude oil offtake by 17 percent; elimination of the demand for high octane gasoline would increase the thermal efficiency of the production of road fuels by 5 percent; replacement of the gasoline engine by diesel or stratified charge engines could reduce the total consumption of automotive fuels by 20 and 10 percent, respectively, and reduce refinery intake by over 25 and 20 percent, respectively; adequate gasoline substitutes can be produced from coal using known technology, but the over-all thermal efficiency of this use of coal is unacceptable because of the 30 to 40 percent efficiency of the fuel production process and the moderate fuel economy of the gasoline engine; replacement of the gasoline engine by the diesel engine could reduce the consumption of coal for automotive purposes by 20 percent and replacement of both by the spark-assisted diesel engine could reduce consumption by 60 percent; the Stirling engine is comparable to the spark-assisted diesel but is bulky and unproven.

    Simulations in automotive industry need more advanced material models to achieve highly reliable forming and springback predictions. Conventional material models implemented in the FEM-simulation models are not capable to describe the plastic material behaviour during monotonic strain paths with sufficient accuracy. Recently, ESI and Corus co-operate on the implementation of an advanced material model in the FEM-code PAMSTAMP 2G. This applies to the strain hardening model, the influence of strain rate, and the description of the yield locus in these models. A subsequent challenge is the description of the material after a change of strain path. The use of advanced high strength steels in the automotive industry requires a description of plastic material behaviour of multiphase steels. The simplest variant is dual phase steel consisting of a ferritic and a martensitic phase. Multiphase materials also contain a bainitic phase in addition to the ferritic and martensitic phase. More physical descriptions of strain hardening than simple fitted Ludwik/Nadai curves are necessary. Methods to predict plastic behaviour of single-phase materials use a simple dislocation interaction model based on the formed cells structures only. At Corus, a new method is proposed to predict plastic behaviour of multiphase materials have to take hard phases into account, which deform less easily. The resulting deformation gradients create geometrically necessary dislocations. Additional micro-structural information such as morphology and size of hard phase particles or grains is necessary to derive the strain hardening models for this type of materials. Measurements available from the Numisheet benchmarks allow these models to be validated. At Corus, additional measured values are available from cross-die tests. This laboratory test can attain critical deformations by large variations in blank size and processing conditions. The tests are a powerful tool in optimising forming simulations

    With the number of automotive sensors increasing, the effort for connecting all these sensors becomes more and more of an issue. A possible way to overcome these issues is to use energy-autonomous sensors that, besides the basic sensor function, include means to transmit the measurement data wirelessly as well as to generate the electrical energy they need to operate. Generating the electrical energy can be done by harvesting energy from ambient sources that are available in abundance, among others these can be heat and vibration. Although these principles are not new, so far little attempts have been made to incorporate these technologies into cost-sensitive segments like the automotive market. In this paper we present two energy-autonomous sensor demonstrators for automotive applications: a temperature sensor powered with a thermoelectric harvester, thus using a tiny amount of the physical property it wants to measure, and a pressure sensor powered by vibration energy. For both applications, managing the limited amount of available energy is one of the mayor tasks in developing this kind of systems. Therefore both systems use special means in hard- and software to cope with that task. While the automotive market is a very interesting one for energy-autonomous sensors, many other possible applications can be considered, among them the solar market and industrial condition monitoring.

    Full Text Available The South African automotive industry, which is an important sector in the South African economy, needs to function efficiently if it is to compete internationally. However, South African automotive components manufacturers (ACMs are not internationally competitive and automotive assemblers, also known as original equipment manufacturers (OEMs, often import cheaper components from abroad. All parties in the South African automotive supply chains need each other to ensure optimal efficiency and competitiveness. Furthermore, it is vital that good relationships exist between customers and suppliers in the automotive supply chains in South Africa. ACMs are central to automotive supply chains. A survey was conducted among ACMs to determine the nature of relationships that exist between buyers and suppliers in South Africa’s automotive supply chains. The results showed that collaborative relationships do indeed exist between members of the supply chain but that communication, understanding of the parties’ situations and cooperation can improve this relationship and so create total alliance between OEMs and ACMs.

    The long-term strategy of the automotive industry is to minimize its CO{sub 2} emissions and to progressively abandon petroleum. Today, the diesel technology is the most efficient in terms of CO{sub 2} emissions and the hybrid technology will be the medium-term challenge with the development of biofuels and synthetic fuels from biomass. According to the author, there is no certitude that the hydrogen fuel cell will be tomorrows' automobile engine and the nuclear option would be necessary to produce huge quantities of hydrogen without CO{sub 2} emissions. The alternate strategies with interesting potentialities remain the electric-powered vehicle supplied with batteries or supplied with methanol fuel cells, methanol being obtained by biomass transformation.

    This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of

    One way of weight reduction in automotive vehicles is through the use of high strength and low alloy (HSLA) steels, which enables the use of small thickness plates. Whereas the appearance of residual stresses is intrinsic to the welding process, this study evaluates the residual stresses generated in welded joints obtained by TIG and LASER welding processes and comparing them. Residual stresses were measured by X-rays diffraction technique, using a portable device with Cr{kappa}{alpha} radiation applying the double exposure method. It also evaluates the influence of shot peening treatment applied after welding, in the bend tests conducted for both welding conditions and TIG welded joints showed higher stability of compressive stresses after welding. The metallographic analysis by optical microscopy complemented the welded joints characterization. (author)

    The United States Automotive Materials Partnership LLC (USAMP) was formed in 1993 as a partnership between Chrysler Corporation, Ford Motor Company, and General Motors Corporation. Since then the U.S. Department of Energy (DOE) has supported its activities with funding and technical support. The mission of the USAMP is to conduct vehicle-oriented research and development in materials and materials processing to improve the competitiveness of the U.S. Auto Industry. Its specific goals are: (1) To conduct joint research to further the development of lightweight materials for improved automotive fuel economy; and (2) To work with the Federal government to explore opportunities for cooperative programs with the national laboratories, Federal agencies such as the DOE and universities. As a major component of the DOE's Office of FreedomCAR and Vehicle Technologies Program (FCVT) collaboration with the USAMP, the Automotive Lightweighting Materials (ALM) program focuses on the development and validation of advanced materials and manufacturing technologies to significantly reduce automotive vehicle body and chassis weight without compromising other attributes such as safety, performance, recyclability, and cost. The FCVT was announced in FY 2002 and implemented in FY 2003, as a successor of the Partnership for a New Generation of Vehicles (PNGV), largely addressed under the first Cooperative Agreement. This second USAMP Cooperative Agreement with the DOE has expanded a unique and valuable framework for collaboratively directing industry and government research efforts toward the development of technologies capable of solving important societal problems related to automobile transportation. USAMP efforts are conducted by the domestic automobile manufacturers, in collaboration with materials and manufacturing suppliers, national laboratories, universities, and other technology or trade organizations. These interactions provide a direct route for implementing newly

    Full Text Available Purpose: The purpose of the article is to report on research that was completed to explore the concept of the bullwhip effect in supply chains and to illustrate empirically the presence of the bullwhip effect in automotive supply chains in South Africa. Problem Investigated: This article investigates the presence of the bullwhip effect - which was identified through an empirical study - and its causes and implications for supply chain management in the South African automotive component industry. Methodology: A literature study was conducted on the causes and implications of the bullwhip effect phenomenon. This was followed by an empirical study in the form of a survey among South African automotive component manufacturers. Descriptive and inferential statistics were used to determine the significant supply chain problems relating to the bullwhip effect in automotive supply chains. Findings and Implications: The results indicate that automotive component manufacturers are dependent on demand-forecasting information from their customers. They experience long lead times, fluctuating orders, cancellation of orders, excess and slow moving inventory and a lack of integration with suppliers and customers. There are also signs of relationship problems and a possible silo mentality. The mentioned results indicate the presence of the bullwhip effect in South African automotive supply chains. Since the bullwhip effect can have a major impact on organisations' costs, knowing where to invest effort and resources should be a high priority for supply chain managers. Value of the Research: Since the field of supply chain management is extremely dynamic, this article contributes to the body of knowledge and provides new insight into the bullwhip effect phenomenon. The results included in this article could assist parties in automotive supply chains to focus their attention on problems that might be within their control and if solved could lead to improved

    Full Text Available Background: The South African automotive industry includes complete supply chains. The South African automotive supply chain stakeholders operating within the global arena are faced with opportunities as well as challenges. The South African government supports the automotive industry and encourages the vision to drastically expand the industry by the year 2020. However, having to adhere to strict prescriptions from customers regarding product quality and logistics, automotive component suppliers have only the actual relationship with customers through which value can be added. Literature acknowledges the importance of relationship value and agrees that it results in business retention. However, literature fails to prove whether relationship value can result in business expansion where more business is generated.Objectives: The objective of this article was to provide a better understanding of how to optimise relationship value within the South African automotive supply chains between Tier 1 and Tier 2 suppliers. Furthermore, the correlation between relationship value and business expansion was tested through a linear regression model. It was also important to determine whether supply chain stakeholders from different countries of origin and cultural backgrounds attach the same importance to relationship value.Method: This article reports on research which followed a positivistic paradigm, through a quantitative study undertaken in the South African automotive supply chains. Members of the National Association for Automobile Component and Allied Manufacturers of South Africa (NAACAM, defined as Tier 1 suppliers, were approached to describe their best Tier 2 suppliers. Questions relating to relationship value and business expansion were asked via a closed-ended questionnaire. The aim was to obtain the perceptions of Tier 1 suppliers of their best Tier 2 suppliers in terms of relationship value and business expansion. The data were analysed

    The reduction of total vehicle weight and lowering of moving masses within the engine are key elements to overcome future emission challenges of the automotive industry. Within a German BMBF funded project the melt spinning technology will be driven to a series production status. The very fast cooling condition of the melt leads to a nano-structure of the aluminium material. This results in new material properties of known alloys. The strength increases dramatically without lowered forming behaviour. With this process the freedom of designing complex alloys is very flexible. Different alloys have been investigated for several applications, where high strength at room and elevated temperatures and/or high wear resistance is required. This paper presents some results regarding the processing, microstructure and mechanical properties of a developed Al-Ni-Fe alloy. This joined research project with partners from the automotive industry as well as automotive suppliers and universities is funded by the German BMBF "NanoMobile" Program under Project number 03X3008.

    Over 400 million used automotive oil filters are discarded in the United States each year, most of which are disposed of in landfills wasting valuable resources and risking contamination of ground- and surface-water supplies. This article summarizes U.S. bureau of Mines research evaluating scrap prepared from used automotive oil filters. Experimental results show that crushed and drained oil filters have a bulk density that is higher than many typical scrap grades, a chemical analysis low in residual elements (except tin due to use of tin plate in filters), and an overall yield, oil-filter scrap to cast steel, of 76% to 85%, depending on the method used to prepare the scrap.

    Bekaslan, A. Ebru

    The future of the transportation sector has significant implications for the mitigation of climate change through reduced GHG emissions as well as achieving energy efficiency and energy independence. Battery-powered, plug-in, and hybrid electric vehicles are widely seen as the greatest source of a solution. This thesis analyzes the historical development and growth of the automotive industry as well as the restructuring toward the next generation technologies in comparison with the U.S. and China to shed light on the question of how a developing country can structure its strategies to be able to upgrade and be competitive over time. Conventional business models can become obsolete. Companies will find it difficult to maintain their market position unless they gain new perspectives on the outlook of the industry as a whole, and take into account the successful business models of tomorrow. The potential for further growth of the Turkish automotive supplier base particularly in the next generation of automotive technologies is therefore highly dependent on policies and strategies at the national level as much as its dependence on the global strategies of the automotive industry's major players. In this sense, the key questions that motivate this study are whether there are foreseeable technological changes and product-segmentation strategies that could significantly enhance the competitiveness of local Turkish suppliers of automotive components. The thesis builds on the theory of innovative enterprise and evolutionary agglomeration to examine the competitive potential of the Konya Auto Part Suppliers' Cluster in Turkey.

    The main motivating factor driving this research is to find differences between the automotive related companies in Malaysia and Indonesia with regard to quality engineering (QE) implementation. A comparative study between Malaysia and Indonesia provides the opportunity to gain perspective and thorough understanding of the similarities and differences on the critical factors for successful QE practices in the context of both these countries. Face to face interviews are used to compare the QE practices in two automotive companies in Malaysia and Indonesia, respectively. The findings of study showed that both countries have clear quality objectives to achieving zero defects in processes and products and total customer satisfaction. Top and middle management in both countries were found to be directly involved in quality improvement on the shop floor to provide On-The-Job training and actively encourage team members to perform quality problem solving through the formation of quality control circles (QCC) particularly in Indonesia automotive industry. In Malaysia automotive industry, the implementation was not fully effective, but they have started to cultivate those values in the daily execution. Based on the case study results and analysis, the researcher has provided suggestions for both countries as an improvement plan for successful QE implementation. These recommendations will allow management to implement appropriate strategies for better QE implementation which hopefully can improve company's performance and ultimately the making the automotive industry in both countries to reach world class quality. It is strongly believed that the findings of this study can help Malaysia and Indonesia automotive industries in their efforts to become more effective and competitive.

    2015-03-01

    Considerable fuel energy, as much as 70%, is not converted to useful work by internal combustion engines but is instead rejected as waste heat, and more than half of the waste heat, nearly 40% of fuel energy, is contained in vehicle exhaust gas. This provides an opportunity to recover some of the wasted fuel energy and convert it from heat into useful work, subject to the laws of thermodynamics, and thereby improve vehicle energy efficiency. Thermoelectric (TE) materials have been extensively researched and TE devices are now being developed for operation at high temperatures corresponding to automotive exhaust gases for direct solid-state conversion of heat into electricity. This has stimulated substantial progress in the development of practical TE generator (TEG) systems for large-scale commercialization. A significant enabler of this progress has been the US Department of Energy's Vehicle Technologies Program through funding for low cost solutions for automotive TE waste heat recovery to improve fuel economy. Our current project at General Motors has culminated in the identification of the potential supply chain for all components and assembly of an automotive TEG. A significant focus has been to develop integrated and iterative modeling tools for a fully optimized TEG design that includes all components and subsystems (TE modules, heat exchangers, thermal interfaces, electrical interconnects, power conditioning, and vehicle integration for maximal use of TEG power). We have built and tested a new, low-cost Initial TEG prototype based on state-of-the-art production-scale skutterudite TE modules, novel heat exchanger designs, and practical solutions to the many technical challenges for optimum TEG performance. We will use the results for our Initial TEG prototype to refine our modeling and design tools for a Final automotive TEG system prototype. Our recent results will be presented. Thanks to: J.R.

    2003-09-24

    Fault tree analysis (FTA) evolved from the aerospace industry in the 1960's. A fault tree is deductive logic model that is generated with a top undesired event in mind. FTA answers the question, ''how can something occur?'' as opposed to failure modes and effects analysis (FMEA) that is inductive and answers the question, ''what if?'' FTA is used in risk, reliability and safety assessments. FTA is currently being used by several industries such as nuclear power and chemical processing. Typically the automotive industries uses failure modes and effects analysis (FMEA) such as design FMEAs and process FMEAs. The use of FTA has spread to the automotive industry. This paper discusses the use of FTA for automotive applications. With the addition automotive electronics for various applications in systems such as engine/power control, cruise control and braking/traction, FTA is well suited to address failure modes within these systems. FTA can determine the importance of these failure modes from various perspectives such as cost, reliability and safety. A fault tree analysis of a car starting system is presented as an example.

    Full Text Available A review of flywheel energy storage technology was made, with a special focus on the progress in automotive applications. We found that there are at least 26 university research groups and 27 companies contributing to flywheel technology development. Flywheels are seen to excel in high-power applications, placing them closer in functionality to supercapacitors than to batteries. Examples of flywheels optimized for vehicular applications were found with a specific power of 5.5 kW/kg and a specific energy of 3.5 Wh/kg. Another flywheel system had 3.15 kW/kg and 6.4 Wh/kg, which can be compared to a state-of-the-art supercapacitor vehicular system with 1.7 kW/kg and 2.3 Wh/kg, respectively. Flywheel energy storage is reaching maturity, with 500 flywheel power buffer systems being deployed for London buses (resulting in fuel savings of over 20%, 400 flywheels in operation for grid frequency regulation and many hundreds more installed for uninterruptible power supply (UPS applications. The industry estimates the mass-production cost of a specific consumer-car flywheel system to be 2000 USD. For regular cars, this system has been shown to save 35% fuel in the U.S. Federal Test Procedure (FTP drive cycle.

    Victor H. López Cortéz

    2010-09-01

    Full Text Available In this work an Advanced High Strength Steel (AHSS sheet of the Transformation Induced Plasticity (TRIP type currently employed in the automotive sector was welded using a Gas Metal Arc Welding (GMAW and a CO2 Laser Beam Welding (LBW processes. The mechanical properties of welded tensile specimens including microhardness were determined and the results were related to the exhibited microstructures. It was found that LBW lead to relatively high hardness in the fusion zone (FZ indicating that the resultant microstructure was predominantly martensite. In the Heat Affected Zone (HAZ, a mixture of phases consisting of bainite and ferrite was present. Similar phase mixtures were found in the HAZ and Fusion Zone (FZ of the GMAW samples. The exhibited microstructure did not result in mechanical degradation when the GMAW specimens were tested in tension as all the fractures occurred in the BM. In contrast, the region adjacent to the HAZ of most tensile specimens welded using LBW failed by brittle cleavage. Apparently, in this region tempering effects due to heat dissipation in the LBW process promoted carbide growth and a relatively coarse microstructure. No embrittlement was found that could be associated with the development of martensite.Neste trabalho, uma chapa de aço de alta resistência (AHSS - Advanced High Strength Steel tipo TRIP (Transformation Induced Plasticity empregado atualmente no setor automotivo foi soldado usando o processo de soldagem a arco com arame solido sob proteção gasosa (GMAW e soldagem com LASER de CO2 (LBW. As propriedades mecânicas das amostras soldadas quanto a tração e microdureza foram determinadas e os resultados foram relacionados com as microestruturas apresentadas.

    2017-01-01

    The development processes used in automotive radio-navigation projects are constantly under adaption pressure. While the software development models are based on automotive production processes, the integration of peripheral components into an automotive system will trigger a high number of requirement modifications. The use of traditional development models in automotive industry will bring team’s development capacity to its boundaries. The root cause lays in the inflexibility of actual processes and their adaption limits. This paper addresses a new project management approach for the development of radio-navigation projects. The understanding of weaknesses of current used models helped us in development and integration of agile methodologies in traditional development model structure. In the first part we focus on the change management methods to reduce request for change inflow. Established change management risk analysis processes enables the project management to judge the impact of a requirement change and also gives time to the project to implement some changes. However, in big automotive radio-navigation projects the saved time is not enough to implement the large amount of changes, which are submitted to the project. In the second phase of this paper we focus on increasing team capacity by integrating at critical project phases agile methodologies into the used traditional model. The overall objective of this paper is to prove the need of process adaption in order to solve project team capacity bottlenecks.

    2009-03-01

    Full Text Available Reverse engineering (RE is a powerful tool for generating a CAD model from the 3D scan data of a physical part that lacks documentation or has changed from the original CAD design of the part. The process of digitizing a part and creating a CAD model from 3D scan data is less time consuming and provides greater accuracy than manually measuring the part and designing the part from scratch in CAD. 3D optical scanning technology is one of the measurement methods which have evolved over the last few years and it is used in a wide range of areas from industrial applications to art and cultural heritage. It is also used extensively in the automotive industry for applications such as part inspections, scanning of tools without CAD definition, scanning the casting for definition of the stock (i.e. the amount of material to be removed from the surface of the castings model for CAM programs and reverse engineering. In this study two scanning experiments of automotive applications are illustrated. The first one examines the processes from scanning to re-manufacturing the damaged sheet metal cutting die, using a 3D scanning technique and the second study compares the scanned point clouds data to 3D CAD data for inspection purposes. Furthermore, the deviations of the part holes are determined by using different lenses and scanning parameters.

  3. Investigation of metallurgical coatings for automotive applications

    Science.gov (United States)

    Su, Jun Feng

    Metallurgical coatings have been widely used in the automotive industry from component machining, engine daily running to body decoration due to their high hardness, wear resistance, corrosion resistance and low friction coefficient. With high demands in energy saving, weight reduction and limiting environmental impact, the use of new materials such as light Aluminum/magnesium alloys with high strength-weight ratio for engine block and advanced high-strength steel (AHSS) with better performance in crash energy management for die stamping, are increasing. However, challenges are emerging when these new materials are applied such as the wear of the relative soft light alloys and machining tools for hard AHSS. The protective metallurgical coatings are the best option to profit from these new materials' advantages without altering largely in mass production equipments, machinery, tools and human labor. In this dissertation, a plasma electrolytic oxidation (PEO) coating processing on aluminum alloys was introduced in engine cylinder bores to resist wear and corrosion. The tribological behavior of the PEO coatings under boundary and starve lubrication conditions was studied experimentally and numerically for the first time. Experimental results of the PEO coating demonstrated prominent wear resistance and low friction, taking into account the extreme working conditions. The numerical elastohydrodynamic lubrication (EHL) and asperity contact based tribological study also showed a promising approach on designing low friction and high wear resistant PEO coatings. Other than the fabrication of the new coatings, a novel coating evaluation methodology, namely, inclined impact sliding tester was presented in the second part of this dissertation. This methodology has been developed and applied in testing and analyzing physical vapor deposition (PVD)/ chemical vapor deposition (CVD)/PEO coatings. Failure mechanisms of these common metallurgical hard coatings were systematically

    This report provides recommended durability-based design properties and criteria for a quasi-isotropic carbon-fiber composite for possible automotive structural applications. The composite, which was made by a rapid molding process suitable for high-volume automotive applications, consisted of continuous Thornel T300 fibers (6K tow) in a Baydur 420 IMR urethane matrix. The reinforcement was in the form of four {+-}45{sup o} stitch-bonded mats in the following layup: [0/90{sup o}/{+-}45{sup o}]{sub S}. This material is the second in a progression of three candidate thermoset composites to be characterized and modeled as part of an Oak Ridge National Laboratory project entitled Durability of Carbon-Fiber Composites. The overall goal of the project, which is sponsored by the U.S. Department of Energy's Office of Advanced Automotive Technologies and is closely coordinated with the industry Automotive Composites Consortium, is to develop durability-driven design data and criteria to assure the long-term integrity of carbon-fiber-based composite systems for large automotive structural components. This document is in two parts. Part I provides the design criteria, and Part 2 provides the underlying experimental data and models. The durability issues addressed include the effects on deformation, strength, and stiffness of cyclic and sustained loads, operating temperature, automotive fluid environments, and low-energy impacts (e.g., tool drops and kickups of roadway debris). Guidance is provided for design analysis, time-dependent allowable stresses, rules for cyclic loadings, and damage tolerance design guidance, including the effects of holes. Chapter 6 provides a brief summary of the design criteria.

    McAuley, John W

    2003-12-01

    The number of light vehicle registrations is forecast to increase worldwide by a factor of 3-5 over the next 50 years. This will dramatically increase environmental impacts worldwide of automobiles and light trucks. If light vehicles are to be environmentally sustainable globally, the automotive industry must implement fundamental changes in future automotive design. Important factors in assessing automobile design needs include fuel economy and reduced emissions. Many design parameters can impact vehicle air emissions and energy consumption including alternative fuel or engine technologies, rolling resistance, aerodynamics, drive train design, friction, and vehicle weight. Of these, vehicle weight is key and will translate into reduced energy demand across all energy distribution elements. A new class of vehicles is needed that combines ultra-light design with a likely hybrid or fuel cell engine technology. This could increase efficiency by a factor of 3-5 and reduce air emissions as well. Advanced lightweight materials, such as plastics or composites, will need to overtake the present metal-based infrastructure. Incorporating design features to facilitate end-of-life recycling and recovery is also important. The trend will be towards fewer materials and parts in vehicle design, combined with ease of disassembly. Mono-material construction can create vehicle design with improved recyclability as well as reduced numbers of parts and weight.

    2012-09-01

    Full Text Available The current safety requirements, environmental impacts and performance have been ledding the automotive industry to search for new alternatives, not just for new car bodies materials, also for new sheet surface treatments as well, used in the painting process in order to fit simultaneous, environmental requirements and corrosion resistance maintenance, that are the key feature guarantees offered by automakers and are also vital to the durability of the vehicle. This fact is of great importance considering that, besides the various types of steels and their metalic coatings, another factor that directly influences the corrosion resistance is the painting system used. Within this context, the GMB, in partnership with CSN, has been performing several works by adding the knowledge of the supplier to automotive technology. An example of this partnership we have the present study, which aimed to, comparatively, evaluate the corrosion resistance of two systems of painted galvanized steel, the first one with pre-treatment based on a traditional phosphate, and the another one based on a nano-ceramic film. In this study, was found out that materials with pre-treatment based on results of nanotechnology showed similar corrosion resistance comparing the phosphatized materials in a traditional way.

    Kolmanovsky, Ilya; Steinbuch, Maarten; Re, Luigi

    2014-01-01

    This book demonstrates the use of the optimization techniques that are becoming essential to meet the increasing stringency and variety of requirements for automotive systems. It shows the reader how to move away from earlier  approaches, based on some degree of heuristics, to the use of  more and more common systematic methods. Even systematic methods can be developed and applied in a large number of forms so the text collects contributions from across the theory, methods and real-world automotive applications of optimization. Greater fuel economy, significant reductions in permissible emissions, new drivability requirements and the generally increasing complexity of automotive systems are among the criteria that the contributing authors set themselves to meet. In many cases multiple and often conflicting requirements give rise to multi-objective constrained optimization problems which are also considered. Some of these problems fall into the domain of the traditional multi-disciplinary optimization applie...

    2016-06-01

    Full Text Available Many industries, for example automotive, have well defined product development process definitions and risk evaluation methods. The FMEA (Failure Mode and Effects Analysis is a first line risk analysis method in design, which has been implemented in development and production since decades. Although the first applications were focusing on mechanical and electrical design and functionalities, today, software components are implemented in many modern vehicle systems. However, standards or industry specific associations do not specify any “best practice” how to design the interactions of multiple entities in one model. This case study focuses on modelling interconnections and on the improvement of the FMEA modelling process in the automotive. Selecting and grouping software components for the analysis is discussed, but software architect design patterns are excluded from the study.

    Full Text Available The purpose of this article is to demonstrate the development of a supply chain model for the automotive industry that would respond to changing consumer demand. Now more than ever, businesses need to improve the efficiency of their supply chains in order to maintain a competitive advantage. The principles of lean manufacturing and just-intime (JIT inventory control that were renowned for helping companies like Toyota, Dell and Walmart to rise to the top of their respective industries are no longer adequate. Leading companies are applying new technologies and sophisticated analytics to make their supply chains more responsive to customer demand. This challenge is driven by fierce competition, fluctuating market demand and rising customer requirements that have led to customers becoming more demanding with increased preferences. The article is based on theoretical reviews and suggests guidelines for the implementation of an automotive supply chain model for a demand-driven environment.

    Even if the air conditioning is switched off, the internal combustion engine in today’s cars continues to drive the common compressor. To avoid resulting power losses, the automotive industry aspires to apply electromagnetic clutches. When the air conditioning is used, however, CO2-emission increases significantly because the electromag-netic coil consumes electricity. The CO2-reduction per year is consequently very low, which is why new compressor clutches were developed that do not require ...

    Full Text Available The current trend in automotive industry is to achieve compact, efficient, reliable systems. Engine timing drives used in engines are one of the most critical systems. Timing belts are subjected to excessive elongation and wear, while timing gears contribute excess mass and inertia in the system. Hence timing chains are preferred widely, in various high performance engines. Chain drives are easy to assemble and adjust, highly efficient, durable, reliable, compact and capable of attaining a wide range of power and speed capacities. In spite of these advantages their complex dynamic behaviour is not well researched. With the improvement of the speed and load of the automotive engine, and silent chain technology, as silent chain has a compact structure, high transmitting efficiency, high reliability and high wear resistance, its vibration and noise is low, and the silent chain have the advantage of life-long maintenance-free, it significant overcomes the gear drive and belt drive performance, therefore, the silent chain is increasingly widely used in automotive engine timing system. In this present review dynamic analysis as well as analysis of automotive engines timing silent chain system are studied.

  6. Third annual report to Congress on the automotive technology development program

    Energy Technology Data Exchange (ETDEWEB)

    1982-03-01

    The Automotive Propulsion Research and Development Act of 1978 focused on advancing the technology of automotive propulsion systems. In formulating the Act, Congress found that: (1) existing automobiles do not meet the Nation's long-term environmental and energy goals; (2) insufficient resources are being devoted to research and development (R and D) on advanced automobile propulsion systems; (3) with sufficient R and D, alternatives to existing systems could meet long-term goals at reasonable cost; and (4) expanded R and D would complement and stimulate corresponding private sector efforts. Because of the Nation's energy problems, Congress felt that advanced automobile propulsion system technology should be developed quickly. Through the Act, Congress expressed its intent for the Department of Energy (DOE) to: (1) make R and D contracts and grants for development of advanced automobile propulsion systems within five years, or within the shortest practicable time consistent with appropriate R and D techniques; (2) evaluate and disseminate information about advanced automobile propulsion system technology; (3) preserve, enhance, and facilitate competition in R and D of existing and alternative automotive propulsion systems; and (4) supplement, but neither supplant nor duplicate, private industry R and D efforts. Summaries of the status of conventional powertrain technology, automotive technology development program, and the management plan and policy transition are given. Tables on contracts and grant procurement for advanced gas turbine engine systems, advanced Stirling engine systems, and the vehicle systems project are given. (WHK)

    The currently completed ILIPT (Intelligent Logistics for Innovative Product Technologies) project was concerned with the concept of the “5 day car” (a customized car that is delivered within five days after its ordering) and encompassed extensive research on the required production and logistics network structures and processes. As car manufacturers in the automotive industry (commonly referred to as OEMs) rely heavily on their suppliers, the major challenge lies in the organization of inter-enterprise cooperation supported by information systems (IS) in an efficient manner. A common understanding of supply chain concepts is indispensable for this. Ontologies as formal representations of concepts can be used as a semantic basis for cooperation. Relevant results from ILIPT are presented followed by a concept as well as a prototype of how to transfer the theoretical findings to a practical implementation, in this case a multi-agent system.

    Full Text Available The local automotive suppliers are facing a number of important challenges such asglobalisation, new requirement in market specifications and the competition brought about by theAsean Free Trade Area (AFTA agreements. In an effort to enhance the competitiveness of themanufacturing sector, the government has implemented the Second Industrial Master Plan, IMP2(1996-2005. The focus of the IMP2 is more on innovation and applications of new technologies, sothat industries can move up the value chain of their activities. Innovative capabilities achieved fromcompanies’ new product development activities have been recognized to be crucial for companies tosustain their competitiveness and organisational success. The importance of product development ismost obvious in the context of the discussion on the competitiveness of the Malaysian automotivesuppliers. The study will focus on the small medium enterprises (SMEs that make up more than 60 %of these automotive suppliers. The study is to determine the extensiveness of the suppliers’ productdevelopment activities by examining the involvement of the suppliers in customer’s productdevelopment activities. Consequently, the impact of this involvement to the competitiveness of thesuppliers is examined. The results were established based from a survey to parts and componentssuppliers of Proton, the Malaysian car national assembler. The study has shown that the SMEs wereinvolved from the early stages of the product development process that is during the design stage. Theproduct development efforts have shown to contribute towards increasing firms’ market share andfirms were also able to gain a better understanding of future product demand. A significant number ofthe suppliers have managed to penetrate the export market. Unfortunately, among the respondents,there is only one system supplier. This indicates that, either the technological capabilities of theSMEs still needed upgrading for the requirement as

    2014-01-01

    Full Text Available Laminated composites are increasingly used in aeronautics and the wind energy industry, as well as in the automotive industry. In these applications, the construction and processing need to fulfill the highest requirements regarding weight and mechanical properties. Environmental issues, like fuel consumption and CO2-footprint, set new challenges in producing lightweight parts that meet the highly monitored standards for these branches. In the automotive industry, one main aspect of construction is the impact behavior of structural parts. To verify the quality of parts made from composite materials with little effort, cost and time, non-destructive test methods are increasingly used. A highly recommended non-destructive testing method is thermography analysis. In this work, a prototype for a car’s base plate was produced by using vacuum infusion. For research work, testing specimens were produced with the same multi-layer build up as the prototypes. These specimens were charged with defined loads in impact tests to simulate the effect of stone chips. Afterwards, the impacted specimens were investigated with thermography analysis. The research results in that work will help to understand the possible fields of application and the usage of thermography analysis as the first quick and economic failure detection method for automotive parts.

Na cadeia tradicional, são examinadas as formas de organização do trabalho de uma fábrica de motores e de dez de seus fornecedores diretos. No caso da planta modular, produtora de caminhões e ônibus, examina-se a organização do trabalho no sistema modular como um todo, explorando-se as peculiaridades deste tipo de arranjo. Os resultados da pesquisa apontam que, na planta modular, a influência da montadora sobre a organização do trabalho configura-se de forma mais direta com relação a salários e jornada de trabalho. Na cadeia tradicional, a influência ocorre de forma indireta, por meio de exigências voltadas para outras áreas de gestão.This paper analyzes the influence that buyer firms have on their suppliers' work organization in two supply chains in the automotive industry. One of the supply chains is controlled by a modular plant and the other is organized in the traditional way. In the traditional supply chain, the work organization of an engine manufacturer plant as well as of ten of its suppliers is examined. In the modular plant, a truck and bus manufacturer, the work organization of the whole modular system is examined, exploring the peculiarities of this kind of arrangement. The results of the research shows that in the modular plant the assembler's influence over the work organization, relating to aspects like wages and work time, is more direct. In the traditional supply chain, the influence happens in a indirect way, through requirements done to other areas of management.

    2016-11-01

    Deep drawn sheet metal parts are increasingly designed to the feasibility limit, thus achieving a robust manufacturing is often challenging. The fluctuation of process and material properties often lead to robustness problems. Therefore, numerical simulations are used to detect the critical regions. To enhance the agreement with the real process conditions, the material data are acquired through a variety of experiments. Furthermore, the force distribution is taken into account. The simulation metamodel contains the virtual knowledge of a particular forming process, which is determined based on a series of finite element simulations with variable input parameters. Based on the metamodels, virtual process windows can be displayed for different configurations. This helps to improve the operating point as well as to adjust process settings in case the process becomes unstable. Furthermore, the time of tool tryout can be shortened due to transfer of the virtual knowledge contained in the metamodels on the optimisation of the drawbeads. This allows the tool manufacturer to focus on the essential, to save time and to recognize complex relationships.

    There are many available strategies to measure employee satisfaction. Among the common strategies are employee responses to supervisors during routine meetings or periodic assessments of performance, number of complaints and feedback from employees. Although the management of the company may expect what its employees are most satisfied with, they may not know what is important to their employees' satisfaction. The "satisfaction attributes" and the "importance attributes" are related components that worth to be taken into account. Besides, the management needs to identify what their employees' priorities are, otherwise the management could be wasting their limited energy and resources tackling wrong attributes. In this study the Important-Satisfaction model is proposed. The model is based on the importance and satisfaction score of the attributes where the score for each attribute is placed in the model. It assists the management in identifying attributes that require improvement and provide an excellent measuring instrument for assessing priorities for attribute improvement.

    The healthcare system is vast in scope, with constant concerns of how the system's major changes will affect the quality of future patient care. This article concerns only one small corner of the healthcare system--pharmaceutical compounding. Despite our best efforts, we are not going to single-handedly change all of the grim statistics, no matter how many years we are given or how much assistance Americans obtain from their international colleagues. Yet, the "good" news is that although in my opinion the overall quality of America's healthcare system has declined, perhaps the modest niche of compounding pharmacy can become a role model of what actually works and can offer immense opportunities to improve the efficiency and effectiveness of health care.

    The additional adhesive bonding of resistance spot welds is a cheap action to get an optimized car body concerning weight, stiffness and strength. The combination of both joining technologies offers an excellent chance to improve the advantages of high strength materials. Regarding to fatigue strength of structures under cyclic load and operational conditions considerable profit can be got by use of weldbonding instead of spotwelding. Both, the stiffness of the parts and the effect of damping within the weldflanges lead to positive effects for the car acoustics. New developed adhesives also show considerable potential with regard to its crash behaviour, offering the opportunity to compensate parts of the latest crash and safety demands to new car generations by improved adhesive systems. Additional adhesive bonding also protects from gapcorrosion within the spotweld flanges over lifetime of the cars. For the selection of adhesives beyond the elementary properties of the joining element adhesive like strength, energy load, long time resistance etc. also production relevant properties have to be taken into consideration. To these properties beside the general suitability for spotwelding also belongs the influence to the choice of the weldparameters, the application technology, the adhesive curing and necessary measures for health protection and cleanness of the production equipment. Alternatives to weldbonding are rivetbonding or clinchbonding. Here exist very interesting chances to translate mixed construction of different materials to the carbody. (orig.) [German] Das zusaetzliche Kleben von Punktschweissverbindungen ist eine kostenguenstige Massnahme zur gewichts-, steifigkeits- und festigkeitsoptimierten Auslegung von Automobilkarosserien. Die Kombination dieser beiden Fuegeverfahren bietet eine ausgezeichnete Moeglichkeit, den Ausnutzungsgrad von hoeher- und hochfesten Werkstoffen deutlich zu verbessern. Besonders hinsichtlich der Schwingfestigkeit und Betriebsfestigkeit lassen sich durch Punktschweisskleben gegenueber dem reinen Punktschweissen erhebliche Gewinne erzielen. Sowohl die hoehere Bauteilsteifigkeit als auch die Daempfungswirkung in den Schweissflanschen bringen positive Effekte fuer die Fahrzeugakustik. Neuentwickelte Klebstoffe zeigen aber auch hinsichtlich ihres Crashverhaltens erhebliches Entwicklungspotenzial auf, das die Moeglichkeit eroeffnet, bei neuen Fahrzeuggenerationen einen Teil der zusatzlichen Crashanforderungen durch verbesserte Klebstoffsysteme zu kompensieren. Ergaenzendes Kleben verhindert Spaltkorrosion in den Punktschweissflanschen ueber die Lebensdauer der Fahrzeuge. Bei der Auswahl sind neben den grundsaetzlichen Eigenschaften des Verbindungselementes Klebstoff, wie Festigkeit, Energieaufnahme, Langzeitbestaendigkeit usw., auch fertigungsrelevante Belange zu beruecksichtigen. Dazu gehoeren neben der generellen Punktschweisseignung der Einfluss auf die Wahl der Schweissparameter, die Applikationstechnologie, die Klebstoffaushaertung sowie die eventuell notwendigen Massnahmen zum Gesundheitsschutz und zur Sauberhaltung der Fertigungsanlagen. Alternativen zum Punktschweisskleben sind das Stanznieten mit Kleben oder auch das Clinchen mit Kleben. Hier eroeffnet sich eine interessante Moeglichkeit zur Umsetzung von Mischbauweise aus unterschiedlichen Werkstoffen. (orig.)

    Taylor, Dalia

    The automotive supply chain and its management can be a very complex process and comprises a long dynamic and complex network that consists of four primary segments: original equipment manufacturers (OEMs), first tier suppliers, sub tiers suppliers, and infrastructure suppliers. During the analysis of the current automotive industry it was identified that textile industry importance is considerable increasing as a part of the global automotive supply chain, because textile products are used for interior, exterior and even suspension parts and components. Automotive industry has an increasing demand for higher quality exterior panels with better functional properties and reduced weight. One of the main potentials for this demand is based on the three-dimensional woven composites technology innovations which can replace an existing technology. The new role of the textile industry could make important changes in the automotive supply chain industry, such as: changes in the size of the supply chain, the time to the market and the position of textile industry in the automotive supply chain structure. 3D composite materials from high performance fibers, such as glass and carbon, have been used for automotive applications in a limited way due to the low production rate and the lack of research and development. This research will contribute to the understanding of textile composites in transportation and the textile parameters that affect the performance characteristics of these materials. The research examines the performance characteristics of lighter and stronger 3D woven fabric composites made from fiberglass with the aim to improve fuel efficiency by reducing the total vehicle weight while maintaining safety standards. The performance characteristics of the 3D woven fabric composite can be designed by changing different construction parameters, such as picks density, pick roving linear density, arrangements of warp and z-yarns, and the number of warp and picks layers

    Beginning the fall semester of 1999, The University of Maryland, Departments of Mechanical and Electrical Engineering and the Institute for Systems Research served as a U.S. Department of Energy (USDOE) Graduate Automotive Technology Education (GATE) Center for Hybrid Electric Drivetrains and Control Strategies. A key goal was to produce a graduate level education program that educated and prepared students to address the technical challenges of designing and developing hybrid electric vehicles, as they progressed into the workforce. A second goal was to produce research that fostered the advancement of hybrid electric vehicles, their controls, and other related automotive technologies. Participation ended at the University of Maryland after the 2004 fall semester. Four graduate courses were developed and taught during the course of this time, two of which evolved into annually-taught undergraduate courses, namely Vehicle Dynamics and Control Systems Laboratory. Five faculty members from Mechanical Engineering, Electrical Engineering, and the Institute for Systems Research participated. Four Ph.D. degrees (two directly supported and two indirectly supported) and seven Master's degrees in Mechanical Engineering resulted from the research conducted. Research topics included thermoelectric waste heat recovery, fuel cell modeling, pre- and post-transmission hybrid powertrain control and integration, hybrid transmission design, H{sub 2}-doped combustion, and vehicle dynamics. Many of the participating students accepted positions in the automotive industry or government laboratories involved in automotive technology work after graduation. This report discusses the participating faculty, the courses developed and taught, research conducted, the students directly and indirectly supported, and the publication list. Based on this collection of information, the University of Maryland firmly believes that the key goal of the program was met and that the majority of the

    Aluminum recycling currently occurs in a cascading fashion, where some alloys, used in a limited number of applications, absorb most of the end-of-life scrap. An expected increase in scrap supply in coming decades necessitates restructuring of the aluminum cycle to open up new recycling paths for alloys and avoid a potential scrap surplus. This paper explores various interventions in end-of-life management and recycling of automotive aluminum, using a dynamic substance flow analysis model of aluminum and its alloying elements with resolution on component and alloy level (vehicle-component-alloy-element model). It was found that increased component dismantling before vehicle shredding can be an effective, so far underestimated, intervention in the medium term, especially if combined with development of safety-relevant components such as wheels from secondary material. In the long term, automatic alloy sorting technologies are most likely required, but could at the same time reduce the need for magnesium removal in refining. Cooperation between the primary and secondary aluminum industries, the automotive industry, and end-of-life vehicle dismantlers is therefore essential to ensure continued recycling of automotive aluminum and its alloying elements.

    In an effort to reduce the weight of vehicles, automotive companies are replacing conventional steel parts with light weight alloys and/or with advanced high strength steels (AHSS) such as dual-phase (DP), twinning induced plasticity (TWIP), and transformation induced plasticity (TRIP) steels. The main objective of this work is to experimentally and numerically evaluate the macro-performance of the automotive TWIP sheet in conjunction with springback. In order to characterize the mechanical properties, simple tension and tension-compression tests were performed to determine anisotropic properties, as well as the Bauschinger, transient, and permanent softening behaviors during reverse loading. For numerical simulations, the anisotropic yield function Yld2000-2d was utilized along with the combined isotropic-kinematic hardening law based on the modified Chaboche model. Springback verification was performed for the unconstrained cylindrical bending and 2D draw bending tests.

    Full Text Available The automotive industry is the key sector of the Czech national economy. Its share on GDP represents more than 8 % and the Czech Republic is the 14th biggest producer of cars in the world. The goal of this article is to analyze the development of the customers´ portfolio of the automotive suppliers in the Czech Republic from the perspective of their international location. The diversification of portfolio can be measured in many ways. The approach in this article relies both on usual statistical tools (concentration ratio, Lorenz curve, Gini coefficient, Herfindahl-Hirschman index and on specific approaches such as number of partners, geographical diversification and average distance travelled by exported component. Even though the export volume has been dynamically growing, it has remained focused on a limited number of crucial countries, which are mostly located in the close neighborhood of the Czech Republic.

    The CRADA between Delphi Automotive Systems (Delphi; formerly General Motors - AC Delco, Systems) and Lockheed Martin Energy Research (LMER) on automotive catalysts was completed at the end of FY96, after a ten month, no-cost extension. The CRADA was aimed at improved performance and lifetime of noble metal based three-way-catalysts (TWC), which are the primary catalytic system for automotive emission control systems. While these TWC can meet the currently required emission standards, higher than optimum noble metal loadings are often required to meet lifetime requirements. In addition, more stringent emission standards will be imposed in the near future, demanding improved performance and service life from these catalysts. Understanding the changes of TWC conversion efficiency with ageing is a critical need in improving these catalysts. Initially in a fresh catalyst, the active material is often distributed on a very fine scale, approaching single atoms or small atomic clusters. As such, a wide range of analytical techniques have been employed to provide high spatial resolution characterization of the evolving state of the catalytic material.

    2005-05-01

    Customer awareness and sensitivity to noise and vibration levels have been raised through increasing television advertisement, in which the vehicle noise and vibration performance is used as the main market differentiation. This awareness has caused the transportation industry to regard noise and vibration as important criteria for improving market shares. One industry that tends to be in the forefront of the technology to reduce the levels of noise and vibration is the automobile industry. Hence, it is of practical interest to reduce the vibrations induced structural responses. The automotive vehicle engine is the main source of mechanical vibrations of automobiles. The engine is vulnerable to the dynamic action caused by engine disturbance force in various speed ranges. The vibrations of the automotive vehicle engines may cause structural failure, malfunction of other parts, or discomfort to passengers because of high level noise and vibrations. The mounts of the engines act as the transmission paths of the vibrations transmitted from the excitation sources to the body of the vehicle and passengers. Therefore, proper design and control of these mounts are essential to the attenuation of the vibration of platform structures. To improve vibration resistant capacities of engine mounting systems, vibration control techniques may be used. For instance, some passive and semi-active dissipation devices may be installed at mounts to enhance vibration energy absorbing capacity. In the proposed study, a radically different concept is presented whereby periodic mounts are considered because these mounts exhibit unique dynamic characteristics that make them act as mechanical filters for wave propagation. As a result, waves can propagate along the periodic mounts only within specific frequency bands called the "Pass Bands" and wave propagation is completely blocked within other frequency bands called the "Stop Bands". The experimental arrangements, including the design of

We examine the impact of the European Parliament, Council (2000 Directive 2000/53/EC on the EU automobile sector reverse logistics activities in the light of the Extended Producer Responsibility (EPR principle. We argue that there is an antinomy in the application of the Directive that is supposed to support an EPR strategy. The antinomy is expressed by [1] the absence of the necessary capabilities of Producer Responsibility Organizations (PROs to advance to higher reverse logistics activities like remanufacturing [2] an indefinite delay of the possibility for transformation of the current forward chain manufacturing model, [3] a stability in the strategic group formation of the European automobile manufacturing sector that prevents the further diffusion of manufacturing and remanufacturing capabilities within EU with profound positive economic impacts in favour of the industrialized countries with a strong automotive manufacturing sector and negative impacts to less industrialized countries. We also argue that the proper application of the EPR strategy is in favour of established EU manufacturers and can act as a barrier to entry for non-European firms.

    Jain, Vipul

    Since the invention of the integrated circuit, the semiconductor industry has revolutionized the world in ways no one had ever anticipated. With the advent of silicon technologies, consumer electronics became light-weight and affordable and paved the way for an Information-Communication-Entertainment age. While silicon almost completely replaced compound semiconductors from these markets, it has been unable to compete in areas with more stringent requirements due to technology limitations. One of these areas is automotive radar sensors, which will enable next-generation collision-warning systems in automobiles. A low-cost implementation is absolutely essential for widespread use of these systems, which leads us to the subject of this dissertation---silicon-based solutions for automotive radars. This dissertation presents architectures and design techniques for mm-wave automotive radar transceivers. Several fully-integrated transceivers and receivers operating at 22-29 GHz and 77-81 GHz are demonstrated in both CMOS and SiGe BiCMOS technologies. Excellent performance is achieved indicating the suitability of silicon technologies for automotive radar sensors. The first CMOS 22-29-GHz pulse-radar receiver front-end for ultra-wideband radars is presented. The chip includes a low noise amplifier, I/Q mixers, quadrature voltage-controlled oscillators, pulse formers and variable-gain amplifiers. Fabricated in 0.18-mum CMOS, the receiver achieves a conversion gain of 35-38.1 dB and a noise figure of 5.5-7.4 dB. Integration of multi-mode multi-band transceivers on a single chip will enable next-generation low-cost automotive radar sensors. Two highly-integrated silicon ICs are designed in a 0.18-mum BiCMOS technology. These designs are also the first reported demonstrations of mm-wave circuits with high-speed digital circuits on the same chip. The first mm-wave dual-band frequency synthesizer and transceiver, operating in the 24-GHz and 77-GHz bands, are demonstrated. All

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The successful application of porous cordierite ceramic monolithic converters for automotive emissions control over the past 24 years in North America has been attributed to systems approach for optimizing the total converter package from reliability point of view. The systems approach examines the interaction between various components of monolithic converter package, namely the cordierite substrate, the alumina washcoat, the braided wire-rope end seals, the intumescent ceramic mat or steel wiremesh, and the stainless steel can, from long-term durability point of view. Such an approach has also proven successful in the Japanese, European, Korean and South American automotive industries. The key objectives of this paper are: i) to describe Corning′s methodology for assessing the impact of alumina washcoat on mechanical and thermal integrities of cordierite converter; ii) to examine the impact of mount density of ceramic mat or steel wiremesh on containment of cordierite converter against engine vibrations, gas pulsations and thermal gradients, and; iii) to analyze the impact of can design on strength and thermal shock resistance of cordierite converter. The above objectives will be illustrated by several examples of successful converter design for automobiles. This paper also addresses the Chinese automotive converter requirements and how they might be met via systems approach.

  9. Applicability valuation for evaluation of surface deflection in automotive outer panels

    Directory of Open Access Journals (Sweden)

    D.H. Park

    2008-12-01

    Full Text Available Purpose: Upon unloading in a forming process there is elastic recovery, which is the release of the elasticstrains and the redistribution of the residual stresses through the thickness direction, thus producing surfacedeflection. It causes changes in shape and dimensions that can create major problem in the external appearanceof outer panels. Thus surface deflection prediction is an important issue in sheet metal forming industry. Manyfactors could affect surface deflection in the process, such as material variations in mechanical properties, sheetthickness, tool geometry, processing parameters and lubricant condition.Design/methodology/approach: Numerical simulation of process was performed by the use of finite elementmethod, paying attention particularly to the thickness distribution and surface deflection of the drawn outerpanel and the outline flange during forming. Simulation procedures of automotive outer panel as large size shapeare as follows; 1 Acquisition of drawing parts 2 Laser scanning for generating CAD model 3 CAD modelgeneration 4 Simulation model operation 5 Simulation execution and analyses of simulation results.Findings: The development of automation in stamping and assembly processes of automobile manufacture willrequire an excellent surface quality of formed panels and also their accurate dimensions.Practical implications: The use of high strength steel sheets in the manufacturing of automobile outer panels hasincreased in the automotive industry over the years because of its lightweight and fuel-efficient improvement.But one of the major concerns of stamping is surface deflection in the formed outer panels. Hence, to be costeffective, accurate prediction must be made of its formability. The automotive industry places rigid constraintson final shape and dimensional tolerances as well as external appearance quality of outer panels. The numericalsimulation makes it possible to design and optimize the total process to a level

  10. Performance evaluation of an automotive thermoelectric generator

    Science.gov (United States)

    Dubitsky, Andrei O.

    Around 40% of the total fuel energy in typical internal combustion engines (ICEs) is rejected to the environment in the form of exhaust gas waste heat. Efficient recovery of this waste heat in automobiles can promise a fuel economy improvement of 5%. The thermal energy can be harvested through thermoelectric generators (TEGs) utilizing the Seebeck effect. In the present work, a versatile test bench has been designed and built in order to simulate conditions found on test vehicles. This allows experimental performance evaluation and model validation of automotive thermoelectric generators. An electrically heated exhaust gas circuit and a circulator based coolant loop enable integrated system testing of hot and cold side heat exchangers, thermoelectric modules (TEMs), and thermal interface materials at various scales. A transient thermal model of the coolant loop was created in order to design a system which can maintain constant coolant temperature under variable heat input. Additionally, as electrical heaters cannot match the transient response of an ICE, modelling was completed in order to design a relaxed exhaust flow and temperature history utilizing the system thermal lag. This profile reduced required heating power and gas flow rates by over 50%. The test bench was used to evaluate a DOE/GM initial prototype automotive TEG and validate analytical performance models. The maximum electrical power generation was found to be 54 W with a thermal conversion efficiency of 1.8%. It has been found that thermal interface management is critical for achieving maximum system performance, with novel designs being considered for further improvement.

  11. Pedestrian recognition using automotive radar sensors

    2012-09-01

    The application of modern series production automotive radar sensors to pedestrian recognition is an important topic in research on future driver assistance systems. The aim of this paper is to understand the potential and limits of such sensors in pedestrian recognition. This knowledge could be used to develop next generation radar sensors with improved pedestrian recognition capabilities. A new raw radar data signal processing algorithm is proposed that allows deep insights into the object classification process. The impact of raw radar data properties can be directly observed in every layer of the classification system by avoiding machine learning and tracking. This gives information on the limiting factors of raw radar data in terms of classification decision making. To accomplish the very challenging distinction between pedestrians and static objects, five significant and stable object features from the spatial distribution and Doppler information are found. Experimental results with data from a 77 GHz automotive radar sensor show that over 95% of pedestrians can be classified correctly under optimal conditions, which is compareable to modern machine learning systems. The impact of the pedestrian's direction of movement, occlusion, antenna beam elevation angle, linear vehicle movement, and other factors are investigated and discussed. The results show that under real life conditions, radar only based pedestrian recognition is limited due to insufficient Doppler frequency and spatial resolution as well as antenna side lobe effects.

  12. Requirements for future automotive batteries - a snapshot

    Karden, Eckhard; Shinn, Paul; Bostock, Paul; Cunningham, James; Schoultz, Evan; Kok, Daniel

    Introduction of new fuel economy, performance, safety, and comfort features in future automobiles will bring up many new, power-hungry electrical systems. As a consequence, demands on automotive batteries will grow substantially, e.g. regarding reliability, energy throughput (shallow-cycle life), charge acceptance, and high-rate partial state-of-charge (HRPSOC) operation. As higher voltage levels are mostly not an economically feasible alternative for the short term, the existing 14 V electrical system will have to fulfil these new demands, utilizing advanced 12 V energy storage devices. The well-established lead-acid battery technology is expected to keep playing a key role in this application. Compared to traditional starting-lighting-ignition (SLI) batteries, significant technological progress has been achieved or can be expected, which improve both performance and service life. System integration of the storage device into the vehicle will become increasingly important. Battery monitoring systems (BMS) are expected to become a commodity, penetrating the automotive volume market from both highly equipped premium cars and dedicated fuel-economy vehicles (e.g. stop/start). Battery monitoring systems will allow for more aggressive battery operating strategies, at the same time improving the reliability of the power supply system. Where a single lead-acid battery cannot fulfil the increasing demands, dual-storage systems may form a cost-efficient extension. They consist either of two lead-acid batteries or of a lead-acid battery plus another storage device.

    2012-06-01

    Full Text Available The study of the thermal, chemical and mechanical properties of pure nickel as an alternative automotive body material is presented in this paper. Current automotive components mainly use steel as the body material. Due to the increasing demand for high performance and related issues, interest is moving towards alternative materials to steel. The hardness values of both heat-treated and non-heat treated pure nickel do not change after annealing; the hardness values are in the range of 118 to 123 HV. As the annealing temperature increases, the ultimate tensile strength, yield strength and Young’s modulus decrease, which indicates that the ductility increases. The highest ultimate tensile strength of pure nickel at 300 °C annealed temperature is 758.78 MPa. X-ray diffraction (XRD studies confirmed pure nickel as a face centred cubic (FCC structure with a lattice constant measured as 0.3492 nm for the unannealed sample, which increases to 0.3512 nm for the annealed samples. The corrosion rate of both annealed and non-heat treated pure nickel is in the range of 0.0266 to 0.048 mm/year.

  1. Challenges and Alternatives to Plastics Recycling in the Automotive Sector

    Directory of Open Access Journals (Sweden)

    Lindsay Miller

    2014-08-01

    Full Text Available Plastics are increasingly a preferred material choice in designing and developing complex, consumer products, such as automobiles, because they are mouldable, lightweight, and are often perceived to be highly recyclable materials. However, actually recycling the heterogeneous plastics used in such durable items is challenging, and presents very different scenarios to how simple products, such as water bottles, are recovered via curbside or container recycling initiatives. While the technology exists to recycle plastics, their feasibility to do so from high level consumer or industrial applications is bounded by technological and economical restraints. Obstacles include the lack of market for recyclates, and the lack of cost efficient recovery infrastructures or processes. Furthermore, there is a knowledge gap between manufacturers, consumers, and end-of-life facility operators. For these reasons, end-of-life plastics are more likely to end up down-cycled, or as shredder residue and then landfilled. This paper reviews these challenges and several alternatives to recycling plastics in order to broaden the mindset surrounding plastics recycling to improve their sustainability. The paper focuses on the automotive sector for examples, but discussion can be applied to a wide range of plastic components from similarly complex products.

    Car fluff is the waste produced after end-of-life-vehicles (ELVs) shredding and metal recovery. It is made of plastics, rubber, glass, textiles and residual metals and it accounts for almost one-third of a vehicle mass. Due to the approaching of Directive 2000/53/EC recycling targets, 85% recycling rate and 95% recovery rate in 2015, the implementation of automotive shredder residue (ASR) sorting and recycling technologies appears strategic. The present work deals with the characterization of the shredder residue coming from an industrial plant, representative of the Italian situation, as for annual fluxes and technologies involved. The aim of this study is to characterize ASR in order to study and develop a cost effective and environmentally sustainable recycling system. Results show that almost half of the residue is made of fines and the remaining part is mainly composed of polymers. Fine fraction is the most contaminated by mineral oils and heavy metals. This fraction produces also up to 40% ashes and its LHV is lower than the plastic-rich one. Foam rubber represents around half of the polymers share in car fluff. Moreover, some chemical-physical parameters exceed the limits of some parameters fixed by law to be considered refuse derived fuel (RDF). As a consequence, ASR needs to be pre-treated in order to follow the energy recovery route.

    2016-03-01

    High power LEDs were introduced in automotive headlights in 2006-2007, for example as full LED headlights in the Audi R8 or low beam in Lexus. Since then, LED headlighting has become established in premium and volume automotive segments and beginning to enable new compact form factors such as distributed low beam and new functions such as adaptive driving beam. New generations of highly versatile high power LEDs are emerging to meet these application needs. In this paper, we will detail ongoing advances in LED technology that enable revolutionary styling, performance and adaptive control in automotive headlights. As the standards which govern the necessary lumens on the road are well established, increasing luminance enables not only more design freedom but also headlight cost reduction with space and weight saving through more compact optics. Adaptive headlighting is based on LED pixelation and requires high contrast, high luminance, smaller LEDs with high-packing density for pixelated Matrix Lighting sources. Matrix applications require an extremely tight tolerance on not only the X, Y placement accuracy, but also on the Z height of the LEDs given the precision optics used to image the LEDs onto the road. A new generation of chip scale packaged (CSP) LEDs based on Wafer Level Packaging (WLP) have been developed to meet these needs, offering a form factor less than 20% increase over the LED emitter surface footprint. These miniature LEDs are surface mount devices compatible with automated tools for L2 board direct attach (without the need for an interposer or L1 substrate), meeting the high position accuracy as well as the optical and thermal performance. To illustrate the versatility of the CSP LEDs, we will show the results of, firstly, a reflector-based distributed low beam using multiple individual cavities each with only 20mm height and secondly 3x4 to 3x28 Matrix arrays for adaptive full beam. Also a few key trends in rear lighting and impact on LED light

  7. Predictive Process Optimization for Fracture Ductility in Automotive TRIP Steels

    Gong, Jiadong

    In light of the emerging challenges in the automotive industry of meeting new energy-saving and environment-friendly requirements imposed by both the government and the society, the auto makers have been working relentlessly to reduce the weight of automobiles. While steel makers pushed out a variety of novel Advanced High Strength Steels (AHSS) to serve this market with new needs, TRIP (Transformation Induced Plasticity) steels is one of the most promising materials for auto-body due to its exceptional combination of strength and formability. However, current commercial automotive TRIP steels demonstrate relatively low hole-expansion (HE) capability, which is critical in stretch forming of various auto parts. This shortcoming on ductility has been causing fracture issues in the forming process and limits the wider applications of this steel. The kinetic theory of martensitic transformations and associated transformation plasticity is applied to the optimization of transformation stability for enhanced mechanical properties in a class of high strength galvannealed TRIP steel. This research leverages newly developed characterization and simulation capabilities, supporting computational design of high-performance steels exploiting optimized transformation plasticity for desired mechanical behaviors, especially for the hole-expansion ductility. The microstructure of the automotive TRIP sheet steels was investigated, using advanced tomographic characterization including nanoscale Local Electrode Atom Probe (LEAP) microanalysis. The microstructural basis of austenite stability, the austenite carbon concentration in particular, was quantified and correlated with measured fracture ductility through transformation plasticity constitutive laws. Plastic flow stability for enhanced local fracture ductility at high strength is sought to maintain high hole-expansion ductility, through quantifying the optimal stability and the heat-treatment process to achieve it.

    A 67 kW (90 hp) Stirling engine design, sized for use in a 1984 1440 kg (3170 lb) automobile was the focal point for developing automotive Stirling engine technology. Since recent trends are towards lighter vehicles, an assessment was made of the applicability of the Stirling technology being developed for smaller, lower power engines. Using both the Philips scaling laws and a Lewis Research Center (Lewis) Stirling engine performance code, dimensional and performance characteristics were determined for a 26 kW (35 hp) and a 37 kW (50 hp) engine for use in a nominal 907 kg (2000 lb) vehicle. Key engine elements were sized and stressed and mechanical layouts were made to ensure mechanical fit and integrity of the engines. Fuel economy estimates indicated that the Stirling engine would maintain a 30 to 45 percent fuel economy advantage comparable spark ignition and diesel powered vehicles in the 1984 period.

    Full Text Available In this paper, an Assembly Line Balancing Problem (ALBP is presented in a real-world automotive cables manufacturer company. This company found it necessary to balance its line, since it needs to increase the production rate. In this ALBP, the number of stations is known and the objective is to minimize cycle time where both precedence and zoning constrains must be satisfied. This problem is formulated as a binary linear program (BLP. Since this problem is NP-hard, an innovative Genetic Algorithm (GA is implemented. The full factorial design is used to obtain the better combination GA parameters and a simple convergence experimental study is performed on the stopping criteria to reduce computational time. Comparison of the proposed GA results with CPLEX software shows that, in a reasonable time, the GA generates consistent solutions that are very close to their optimal ones. Therefore, the proposed GA approach is very effective and competitive.

    Driven by economical and ecological reasons, thermoplastics based coatings were more and more used in automotive engines. Two design concepts, flame spraying and serigraphy PEEK coatings on light metal substrate, were introduced in this paper. The friction and wear behavior of PEEK based coatings were investigated systematically. Coatings with different crystallinities can be obtained when cooling speed is controlled. Among three sprayed coatings considered with different crystallinities, the one with highest crystallinity exhibits best friction and wear behavior under dry sliding condition. Under lubricated sliding condition, however, the amorphous coating gives lower friction coefficient. The micron particles such as SiC,MoS2 and graphite in composite coatings can improve significantly the coating wear resistance and have a impact on coating friction behavior.

    Infrared absorption spectroscopy (IR) and acousto-optic tunable filter (AOTF) technology were combined to develop a portable spectrophotometer for use in engine oil analysis to identify and quantify oil contaminants and residue products, Preliminary measurements were taken with a field-portable AOTF-based spectrometer (2 to 4.5 micrometers ) and an FTIR spectrometer (2 to 25 micrometers ) for comparison. Absorption spectra of used and unused oil samples were measured and compared to determine absorption changes between the various samples resulting from oil degradation and any chemical reactions that might have taken place during high- temperature engine lubrication. These preliminary results indicate that IR spectroscopy can be used for oil quality monitoring in automotive engines, which will help predict and prevent engine failure and degradation. This work can be extended to other remote sensing applications, such as the monitoring of environmental oil spills.

    This research investigates the problem of the part supplier performance evaluation in a major Japanese automotive plant in Thailand. Its current evaluation scheme is based on experiences and self-opinion of the evaluators. As a result, many poor performance suppliers are still considered as good suppliers and allow to supply parts to the plant without further improvement obligation. To alleviate this problem, the brainstorming session among stakeholders and evaluators are formally conducted. The result of which is the appropriate evaluation criteria and sub-criteria. The analytical hierarchy process is also used to find suitable weights for each criteria and sub-criteria. The results show that a newly developed evaluation method is significantly better than the previous one in segregating between good and poor suppliers.

    2013-01-01

    Aero and Vibroacoustics of Automotive Turbochargers is a topic involving aspects from the working fields of thermodynamics of turbomachinery, aerodynamics, rotordynamics, and noise propagation computation.   In this broadly interdisciplinary subject, thermodynamics of turbomachinery is used to design the turbocharger and to determine its operating conditions.  Aerodynamics is needed to study the compressor flow dynamics and flow instabilities of rotating stall and surge, which can produce growling and whining-type noises. Rotordynamics is necessary to study rotor unbalance and self-excited oil-whirl instabilities, which lead to whistling and constant tone-type noises in rotating floating oil-film type bearings. For the special case of turbochargers using ball bearings, some high-order harmonic and wear noises also manifest in the rotor operating range. Lastly, noise propagation computation, based on Lighthill’s analogy, is required to investigate airborne noises produced by turbochargers in passenger vehi...

    Full Text Available Abstract Background In Ethiopia, although there are numerous small-scale and medium industries which use lead-based raw materials that may pose health risks to workers, there are no workplace regulations for lead exposure. Moreover, there are no studies carried out on the blood lead levels (BLLs of workers or on the contribution of common workplace practices to lead poisoning. Method A cross-sectional study on the BLLs of 45 automotive garage workers and 40 non-garage workers was carried out in the town of Jimma, Ethiopia. In addition to BLL analysis, data on some risk factors such as smoking, and chewing ‘khat’ (the leaves of Catha adulis were gathered through structured questionnaires and interviews and data analysis was performed using SPSS (version 16. The t-test was used to compare mean BLLs of study groups. The analysis of variance (ANOVA, Kruskal-Wallis, Pearson chi-square and odds ratio tests were used to investigate the associations between specific job type, smoking and/or ‘khat’ chewing, service years and occurrence of non-specific symptoms with BLLs. Results The mean BLL of the automotive-garage workers was found to be significantly greater than that of the controls. The BLLs of all the lead-exposed individuals were found to be over 10 μg/dL, and 53% of them had BLLs ranging 12 – 20 μg/dL, with the remaining 47% having over 20 μg/dL. The BLL of the workers increased with the duration of working in an automotive garage. Individuals involved in manual car painting comprise a larger percentage (58% of those with the highest BLLs (≥ 20 μg/dL. Lead accumulation in individuals who chew ‘khat’ in the work place was found to be faster than in those who are not used to chewing ‘khat’. ‘Khat’ is an evergreen shrub native to tropical East Africa, with dark green opposite leaves which are chewed when fresh for their stimulating effects. Conclusion The findings of the study have clearly demonstrated that the

    2016-11-01

    Full Text Available In automotive and electronics supply chains, sustainability assessment is gaining increasing importance. More stringent regulations and growing customer pressure are driving the change towards more environmentally, socially and economically responsible supply chains. Since this implies a rising use of resources for data collection, monitoring, exchange and assessment, the objective of this paper is to facilitate supply chain sustainability assessment. The present paper first provides a tailored set of 69 supply chain sustainability indicators for the European automotive and electronics industries. These were derived on the basis of a systematic literature review, together with 13 semi-structured interviews and five focus group workshops, all of which involved sustainability and industry experts. Second, the paper provides a case example of software-based supply chain sustainability data exchange. The extent to which sustainability information is currently exchanged in the two industries is also analyzed. The set of indicators is scientifically relevant since it considers all three dimensions of sustainability and is intended to allow for supply chain-wide sustainability assessment in two specific industries. It is also of high practical relevance since it was developed with and validated by industry experts, and also since it considers industrial and technical requirements for supply chain sustainability assessment in order to increase the efficiency of the work processes.

    2015-12-01

    Full Text Available The main purpose of this paper is to provide an in-depth analysis of the anatomy of China's automotive exports, relying on the literature on firm and product heterogeneity. For this purpose, we use highly disaggregated HS 8-digit product-category level data collected by the Chinese Customs Office for 2000 and 2008, and we distinguish between foreign firms, domestic public firms, and domestic private firms. We also decompose automotive products into autos and auto parts and components (P/C. We then calculate both the extensive margins – number of products exported – and intensive margins – average value of exports per product – of China's automotive exports. We estimate gravity equations to assess the determinants of China's exports of autos and auto P/C. Overall, our analysis yields a number of new, interesting stylized facts about China's automotive exports by confirming the need for taking into account different types of heterogeneity in analyzing international trade.

    A new type of high strength, high toughness, martensitic steel, based on a newly proposed quench and partitioning (Q and P) process, is presented. This high strength martensitic grade is produced by the controlled low temperature partitioning of carbon from as-quenched martensite laths to retained inter-lath austenite under conditions where both low temperature transition carbide formation and cementite precipitation are suppressed. The contribution focuses on both the current understanding of the fundamental processes involved and includes a discussion of the technical feasibility of large-scale industrial production of these steels as sheet products. The Q and P process, which is carried out on steels with a lean composition, should be implemented easily on some current industrial continuous annealing and galvanizing lines. In addition, martensitic Q and P sheet steel is characterized by very favourable combinations of strength, ductility and toughness, which are particularly relevant for high strength anti-intrusion automotive parts.

    2007-01-01

    The tube hydroforming technology is used today in the mass production of lightweight components for the automotive industries due to its advantages over conventional stamping methods. A typical tube hydroforming process is usually a multiple forming operation process. The tube preforming and hydroforming process of an automobile subframe were analyzed by finite element method (FEM), and a parametric study was also carried out to obtain the effect of the forming parameters such as the die closing, the internal pressure and the axial feeding. The simulation results were also compared with industrial products in respect to the thickness distribution of some typical and key cross-sections. The study indicates that the internal pressure and the axial feeding should be set correctly and the multiple forming operations of tube hydroforming process can be simulated well by using the explicit code Ls-Dyna.

    2015-01-01

    Full Text Available The state of catalysts plays a key role in automotive exhaust gas aftertreatment. The soot or ash loading of Diesel particulate filters, the oxygen loading degree in three-way catalysts, the amount of stored ammonia in SCR catalysts, or the NOx loading degree in NOx storage catalysts are important parameters that are today determined indirectly and in a model-based manner with gas sensors installed upstream and/or downstream of the catalysts. This contribution gives an overview on a novel approach to determine the catalyst state directly by a microwave-based technique. The method exploits the fact that the catalyst housing acts as a microwave cavity resonator. As “sensing” elements, one or two simple antennas are mounted inside the catalyst canning. The electrical properties of the catalyst device (ceramic honeycomb plus coating and storage material can be measured. Preferably, the resonance characteristics, e.g., the resonance frequencies, of selected cavity modes are observed. The information on the catalyst interior obtained in such a contactless manner is very well correlated with the catalyst state as will be demonstrated for different exhaust gas aftertreatment systems.

  14. Light source modeling for automotive lighting devices

    Zerhau-Dreihoefer, Harald; Haack, Uwe; Weber, Thomas; Wendt, Dierk

    2002-08-01

    Automotive lighting devices generally have to meet high standards. For example to avoid discomfort glare for the oncoming traffic, luminous intensities of a low beam headlight must decrease by more than one order of magnitude within a fraction of a degree along the horizontal cutoff-line. At the same time, a comfortable homogeneous illumination of the road requires slowly varying luminous intensities below the cutoff line. All this has to be realized taking into account both, the legal requirements and the customer's stylistic specifications. In order to be able to simulate and optimize devices with a good optical performance different light source models are required. In the early stage of e.g. reflector development simple unstructured models allow a very fast development of the reflectors shape. On the other hand the final simulation of a complex headlamp or signal light requires a sophisticated model of the spectral luminance. In addition to theoretical models based on the light source's geometry, measured luminance data can also be used in the simulation and optimization process.

    2003-08-01

    This paper reports an experimental study on active vibration reduction for automotive shafts with the use of piezoelectric material. The work focuses on an axle of an Audi A2. The demand in the automobile sector for higher comfort in the vehicle is of a great importance alongside the requirements of lighter weight and low fuel consumption. These requirements are typically in conflict with each other. One solution is the use of intelligent materials instead of viscoelastic materials and proof mass absorbers. These solutions are quite heavy especially at low frequencies. Active vibration control and piezoelectric devices are advantageous in this application due to their low mass to performance ratio. Our research study explores the use of such piezoelectric devices for an axle. In conjunction with electronics it will reduce vibrations in the first natural bending mode of the axle. Laboratory tests simulated the condition present in the road. At first a stationary set up was used, then a simulated disturbance was input at the attachment points of the shaft. Finally, a test with rotating shaft was performed. Piezoelectric devices (custom QuickPacks from ACX, a Division of Cymer) were used as sensors and as actuators to properly control the axle during the different operating conditions. The power consumption of each actuator pair was less than 20W. The work described here details the test setup, the control strategy, the hardware implementation as well as the test results obtained.

  16. The Cost of Automotive Polymer Composites: A Review and Assessment of DOE's Lightweight Materials Composites Research

    Das, S.

    2001-01-26

    Polymer composite materials have been a part of the automotive industry for several decades, with early application in the 1953 Corvette. These materials have been used for applications with low production volumes, because of their shortened lead times and lower investment costs relative to conventional steel fabrication. Important drivers of the growth of polymer composites have been the reduced weight and parts consolidation opportunities the material offers, as well as design flexibility, corrosion resistance, material anisotropy, and mechanical properties. Although these benefits are well recognized by the industry, polymer composite use has been dampened by high material costs, slow production rates, and to a lesser extent, concerns about recyclability. Also impeding large scale automotive applications is a curious mixture of concerns about material issues such as crash energy absorption, recycling challenges, competitive and cost pressures, the industry's general lack of experience and comfort with the material, and industry concerns about its own capabilities (Flynn and Belzowski 1995). Polymer composite materials are generally made of two or more material components--fibers, either glass or carbon, reinforced in the matrix of thermoset or thermoplastic polymer materials. The glass-reinforced thermoset composites are the most commonly used composite in automotive applications today, but thermoplastic composites and carbon fiber-reinforced thermosets also hold potential. It has been estimated that significant use of glass-reinforced polymers as structural components could yield a 20-35% reduction in vehicle weight. More importantly, the use of carbon fiber-reinforced materials could yield a 40-65% reduction in weight.

    2017-01-01

    An Automotive Electronic Control Units (ECU) development project embedded within a car Environment is constantly under attack of a continuous flow of modifications of specifications throughout the life cycle. Root causes for those modifications are for instance simply software or hardware implementation errors or requirement changes to satisfy the forthcoming demands of the market to ensure the later commercial success. It is unavoidable that from the very beginning until the end of the project “requirement changes” will “expose” the agreed objectives defined by contract specifications, which are product features, budget, schedule and quality. The key discussions will focus upon an automotive radio-navigation (infotainment) unit, which challenges aftermarket devises such as smart phones. This competition stresses especially current used automotive development processes, which are fit into a 4 Year car development (introduction) cycle against a one-year update cycle of a smart phone. The research will focus the investigation of possible impacts of changes during all phases of the project: the Concept-Validation, Development and Debugging-Phase. Building a thorough understanding of prospective threats is of paramount importance in order to establish the adequate project management process to handle requirement changes. Personal automotive development experiences and Literature review of change- and configuration management software development methodologies led the authors to new conceptual models, which integrates into the structure of traditional development models used in automotive projects, more concretely of radio-navigation projects.

    Expanding world economic prosperity and probable peaking of conventional petroleum production in the coming decades require efforts to increase the efficiency of, and the development of alternatives to, petroleum-based fuels used in automotive transportation. North America has been aggressively pursuing both approaches for over ten years. Mainly as a result of lower prices due to global sourcing, magnesium has recently emerged as a serious candidate for lightweighting, and thus increasing the fuel efficiency of, automotive transportation. Automotive vehicles produced in North America currently use more Mg than vehicles produced elsewhere in the world, but the amounts per vehicle are very small in comparison to other materials such as steel, aluminum and plastics. The reasons, besides price, are primarily a less-developed state of technology for Mg in automotive transportation applications and lack of familiarity by the vehicle manufacturers with the material. This paper reviews some publicly-known, recent, present and future North American research and development activities in Mg for automotive applications.

    Modern automotive design has been faced with the weight reduction problem to meet the CO2 emissions standard while achieving high safety and compact design. Such being the case, most car makers want to use the ultra high strength steels (UHSS). But there are several problems when such steels are used, due to presumed lack of formability. Since the disadvantage such as above, it has been suggested that UHSS need special forming methods or it should be used only limited process like simple bending, by many automotive research institutes. To overcome these shortcomings, Twinning Induced Plasticity (TWIP) steel for improved strength and formability has been developed by steel making company, including POSCO, Korea. Because of its characteristics, it is expected to be widely used in automotive parts. This paper aims at finding out several ways how to make effective use of TWIP steel in automotive parts. Especially, comprising about from 15 to 18% manganese and from 1.5 to 2% aluminum which was developed by POSCO for application of the automotive parts will be considered.

  2. Materials Challenges for Automotive PEM Fuel Cells

    Gasteiger, Hubert

    2004-03-01

    Over the past few years, significant R efforts aimed at meeting the challenging cost and performance targets required for the use of Polymer Electrolyte Membrane (PEM) fuel cells in automotive applications. Besides engineering advances in bipolar plate materials and design, the optimization of membrane-electrode assemblies (MEAs) was an important enabler in reducing the cost and performance gaps towards commercial viability for the automotive market. On the one hand, platinum loadings were reduced from several mgPt/cm2MEA [1] to values of 0.5-0.6 mgPt/cm2MEA in current applications and loadings as low as 0.25 mgPt/cm2MEA have been demonstrated on the research level [2]. On the other hand, implementation of thin membranes (20-30 micrometer) [3, 4] as well as improvements in diffusion medium materials, essentially doubled the achievable power density of MEAs to ca. 0.9 W/cm2MEA (at 0.65 V) [5], thereby not only reducing the size of a PEMFC fuel cell system, but also reducing its overall materials cost (controlled to a large extent by membrane and Pt-catalyst cost). While this demonstrated a clear path towards automotive applications, a renewed focus of R efforts is now required to develop materials and fundamental materials understanding to assure long-term durability of PEM fuel cells. This presentation therefore will discuss the state-of-the-art knowledge of catalyst, catalyst-support, and membrane degradation mechanisms. In the area of Pt-catalysts, experience with phosphoric acid fuel cells (PAFCs) has shown that platinum sintering leads to long-term performance losses [6]. While this is less critical at the lower PEMFC operating temperatures (200C), very little is known about the dependence of Pt-sintering on temperature, cell voltage, and catalyst type (i.e., Pt versus Pt-alloys) and will be discussed here. Similarly, carbon-support corrosion can contribute significantly to voltage degradation in PAFCs [7], and even in the PEMFC environment more corrosion

    We have demonstrated for the first time, to our knowledge, the use of optical coherence tomography (OCT) as an analytical tool for nondestructively characterizing the individual paint layer thickness of multiple layered automotive paints. A graph-based segmentation method was used for automatic analysis of the thickness distribution for the top layers of solid color paints. The thicknesses measured with OCT were in good agreement with the optical microscope and ultrasonic techniques that are the current standard in the automobile industry. Because of its high axial resolution (5.5 μm), the OCT technique was shown to be able to resolve the thickness of individual paint layers down to 11 μm. With its high lateral resolution (12.4 μm), the OCT system was also able to measure the cross-sectional area of the aluminum flakes in a metallic automotive paint. The range of values measured was 300-1850  μm2. In summary, the proposed OCT is a noncontact, high-resolution technique that has the potential for inclusion as part of the quality assurance process in automobile coating.

    This paper discusses the implementation of a light emitting diode based visible light communication system for optical vehicle-to-vehicle (V2V) communications in road safety applications. The widespread use of LEDs as light sources has reached into automotive fields. For example, LEDs are used for taillights, daytime running lights, brake lights, headlights, and traffic signals. Future in the optical vehicle-to-vehicle (V2V) communications will be based on an optical wireless communication technology that using LED transmitter and a camera receiver (OCI; optical communication image sensor). Utilization of optical V2V communication systems in automotive industry naturally brings a lot of problems. Among them belongs necessity of circuit implementation into the current concepts of electronic LED lights control that allows LED modulation. These circuits are quite complicated especially in case of luxury cars. Other problem is correct design of modulation circuits so that final vehicle lightning using optical vehicle-to-vehicle (V2V) communication meets standard requirements on Photometric Quantities and Beam Homogeneity. Authors of this article performed research on optical vehicle-to-vehicle (V2V) communication possibilities of headlight (Jaguar) and taillight (Skoda) in terms of modulation circuits (M-PSK, M-QAM) implementation into the lamp concepts and final fulfilment of mandatory standards on Photometric Quantities and Beam Homogeneity.

    We investigate, within the scope of econophysics, the correlations, hierarchies and networks of the world’s automotive companies over the 2003-2010 period by using the concept of a minimal spanning tree (MST) and hierarchical tree (HT). We derive a hierarchical organization and construct the MSTs and HTs for the 2003-2010 period and illustrate how the MSTs and their associated HTs developed over time. These periods are divided into two subperiods, such as 2003-2006 and 2007-2010, in order to test various time-windows and understand the temporal evolution of the correlation structure over time. We perform the bootstrap techniques to investigate a value of the statistical reliability to the links of the MSTs. We also use average linkage cluster analysis (ALCA) to observe the cluster structure more clearly in HTs. From the structural topologies of these trees, we identify different clusters of companies according to their geographical proximity and economic ties. Our results show that some companies are more important within the network, due to a tighter connection with other companies. We also find that these important companies play a predominant role in the world’s automotive industry.

  6. Hot Cutting of Real-Time Cast-Forged GS Ductile Iron for Automotive Rods

    Fouilland, Laurence; Mansori, Mohamed El

    2011-01-01

    In the global economy context, automotive industry suppliers have to keep a constant advance on products design and manufacturing process. Concerning automotive rods, the substitution of forged steel by spherical graphite iron (SG iron) with high mechanical properties constitutes a valid economic alternative. Such rods are produced using a complex coupled process: casting and forging followed by an austempered heat treatment. The forging operation is capable to shape the cast rod which introduces hot deformation to increase mechanical properties of net-shape SG iron rod. However, the intermediate re-heating between casting and forging must be avoided to keep competitive manufacturing costs. A major concern of this new process development is the cracks produced in rod's surface which are consecutive to hot spruing involved after casting operations. This issue is addressed in this paper which discusses the physical mechanisms involved in the hot ductile damage of SG iron. Hot cutting tests were performed to simulate the spruing operation which shows the close interactions between microstructure, machining parameters and resulting damages. The damage mechanisms in terms of crack initiation and its growth have been studied with respect to the constituent phases (austenite+graphite nodules), the cut surface morphology and the hot cutting performance.

    In order to prevent a further increased use of resources and to decrease the environmental impact from landfills, organic wastes are today diverted towards material and energy recovery. This creates a waste market with an increasing number of waste fractions that needs to be treated properly. As an example, in Sweden it has recently been prohibited to landfill source separated combustible waste (2002) and organic waste (2005). Wastes as automotive shredder residue (ASR) and sewage sludge can no longer be landfilled and needs to be either material or energy recovered, which challenge the waste treatment sector. This work investigates the effects of ASR and sewage sludge co-combustion in a 20 MW Energy-from-Waste plant (bubbling fluidised bed). The long term objective of the work is to increase the fuel flexibility, the boiler availability and the power production. This report focus on boiler operation and combustion performance in terms of agglomeration, deposit rates and emissions. In addition to the tests with ASR and sewage sludge, repeated measurements were performed during normal load as a reference. The results show that the co-combusted fractions of ASR and sewage sludge, which on mass basis constituted 6 % and 15 % respectively, did not increase the risk for agglomeration or deposits on heat-exchanging surfaces. Instead, compared to the two reference cases, the deposit rates decreased when sewage sludge was added. Only minor variation in the emissions was seen between the different cases. The levels of I-TEQs were far below the legislated values in all cases

    Kavorkijan, V.

    2003-02-01

    Inadequate wear resistance and low seizure loads prevent the direct use of aluminum alloys in automotive parts subject to intensive friction combined with high thermal and mechanical loading, such as brake discs, pistons, and cylinder liners. To enable the use of aluminum alloys in the production of automotive brake discs and other wear-resistant products, the insertion of a monolithic friction cladding rather than surface coating has been considered in this work. Three experimental approaches, two based on the pressure-less infiltration of porous ceramic preforms and one based on the subsequent hot rolling of aluminum and metal-matrix composite strips, are currently under investigation.

    Although titanium has attractive properties that can improve the performance and economy of automobiles, at its current cost, it cannot compete with steel in most applications for which it is suited. It is readily apparent that titanium cannot be considered a viable mass-market automotive materials alternative as long as it is produced with the Kroll process. A look at existing and new technologies (as well as some that have been found lacking) in terms of applicability toward high-volume, low-cost titanium production for automotive applications indicates other options.

  1. Sliding mode observers for automotive alternator

    Science.gov (United States)

    Chen, De-Shiou

    Estimator development for synchronous rectification of the automotive alternator is a desirable approach for estimating alternator's back electromotive forces (EMFs) without a direct mechanical sensor of the rotor position. Recent theoretical studies show that estimation of the back EMF may be observed based on system's phase current model by sensing electrical variables (AC phase currents and DC bus voltage) of the synchronous rectifier. Observer design of the back EMF estimation has been developed for constant engine speed. In this work, we are interested in nonlinear observer design of the back EMF estimation for the real case of variable engine speed. Initial back EMF estimate can be obtained from a first-order sliding mode observer (SMO) based on the phase current model. A fourth-order nonlinear asymptotic observer (NAO), complemented by the dynamics of the back EMF with time-varying frequency and amplitude, is then incorporated into the observer design for chattering reduction. Since the cost of required phase current sensors may be prohibitive, the most applicable approach in real implementation by measuring DC current of the synchronous rectifier is carried out in the dissertation. It is shown that the DC link current consists of sequential "windows" with partial information of the phase currents, hence, the cascaded NAO is responsible not only for the purpose of chattering reduction but also for necessarily accomplishing the process of estimation. Stability analyses of the proposed estimators are considered for most linear and time-varying cases. The stability of the NAO without speed information is substantiated by both numerical and experimental results. Prospective estimation algorithms for the case of battery current measurements are investigated. Theoretical study indicates that the convergence of the proposed LAO may be provided by high gain inputs. Since the order of the LAO/NAO for the battery current case is one order higher than that of the link

    Six Sigma is a strategy for achieving process improvement and operational excellence within an organization. Decisions on critical parameter selection in analysis phase are always very crucial; it plays a primary role in successful execution of Six Sigma project and for productivity improvement in manufacturing environment and involves the imprecise, vague and uncertain information. Using a case study approach; the paper demonstrates a tactical approach for selection of critical factors of machine breakdown in center less grinding (CLG) section at an automotive industry using fuzzy logic based multi attribute decision making approach. In this context, we have considered six crucial attributes for selection of critical factors for breakdown. Mean time between failure is found to be the pivotal selection criterion in CLG section. Having calculated the weights pertinent to criteria through two methods (fuzzy VIKOR and fuzzy TOPSIS) critical factors for breakdown are prioritized. Our results are in strong agreement with the perceptions of production and maintenance department of the company.

  5. Production of automotive batteries in Russia and other members of the CIS: status, problems and prospects

    Science.gov (United States)

    Soldatenko, V.; Gagarinov, V.

    At present, the total capacity for the production of automotive lead/acid batteries in Russia and other members of the CIS is 10 million units per annum. This capcity should be increased by 4.7 million units in 1996. Nevertheless, environmental problems, plant modernization and shortage of raw materials are expected to cause a decrease in the existing rate of battery production. Russia imported 1.5 million batteries in 1993. The future strategy of the Russian battery industry is two-fold: an expansion of exports; a focus on smaller battery sizes (up to 60 Ah). A major problem lies in the fact that the present market consists predominantly of small consumers that are spread over vast distances. It is therefore critical to establish an effective, new infrastructure for battery distribution.

    Production for the automotive industry must be particularly sensitive to the aspect of safety and reliability of manufactured components. One of such element is the rim, where durability is a feature which significantly affects the safety of transport. Customer complaints regarding this element are particularly painful for the manufacturer because it is almost always associated with the event of accident or near-accident. Authors propose original comprehensive method of quality control at selected stages of rims production: supply of materials, production and pre-shipment inspections. Tests by the proposed method are carried out on the originally designed inertial fatigue machine The machine allows bending fatigue tests in the frequency range of 0 to 50 Hz at controlled increments of vibration amplitude. The method has been positively verified in one of rims factory in Poland. Implementation resulted in an almost complete elimination of complaints resulting from manufacturing and material errors.

    2014-03-01

    Brake squeal is still a major issue in the automotive industry due to comfort complaints of passengers and resulting high warranty costs. Many measures to avoid squeal have been discussed in the engineering community reaching from purely passive measures like the increase of damping, e.g. by the application of shims, to the active or semiactive suppression of squeal. While active measures can be effective but are elaborate and therefore more expensive, passive measure are less complex in most cases. This leads to the necessity to develop passive, economic and robust measures to avoid squeal. Asymmetry of the brake rotor has been proposed to achieve this goal and the resulting split of all double eigenfrequencies of the brake rotor has lately been shown to stabilize the system.

    The Automotive Market offers several opportunities for Dow Corning to leverage the power of silicon-based materials. Dow Corning Photonics Solutions has a number of developments that may be attractive for the emergent photonics needs in automobiles, building on 40 years of experience as a leading Automotive supplier with a strong foundation of expertise and an extensive product offering- from encapsulents and highly reliable resins, adhesives, insulating materials and other products, ensuring that the advantage of silicones are already well-embedded in Automotive systems, modules and components. The recent development of LED encapsulants of exceptional clarity and stability has extended the potential for Dow Corning"s strength in Photonics to be deployed "in-car". Demonstration of board-level and back-plane solutions utilising siloxane waveguide technology offers new opportunities for systems designers to integrate optical components at low cost on diverse substrates. Coupled with work on simple waveguide technology for sensors and data communications applications this suite of materials and technology offerings is very potent in this sector. The harsh environment under hood and the very extreme thermal range that materials must sustain in vehicles due to both their engine and the climate is an applications specification that defines the siloxane advantage. For these passive optics applications the siloxanes very high clarity at the data-communications wavelengths coupled with extraordinary stability offers significant design advantage. The future development of Head-Up-Displays for instrumentation and data display will offer yet more opportunities to the siloxanes in Automotive Photonics.
