2004-01-01

Resumen en español Se describe un proceso integral asistido por computadora del diseño de un reductor de velocidad que incluye el modelado, simulación y dibujo automático. Se aplicó el programa de simulación Powersim para desarrollar un modelo computarizado de la estructura mecánica. Se han desarrollado programas especiales para producir dibujos bidimensionales del ensamble del reductor de velocidad, por medio del lenguaje AutoLISP existente en AutoCAD. Con el fin de obtener el mejor (mas) diseño de las partes, los resultados de los cálculos de Powersim pueden ser transferidos al software Solid Works para el diseño automático tridimensional de partes seleccionadas, utilizando el método de modelado sólido. Con la aplicación del software de elementos finitos es posible crear una malla automática y el desarrollo de un análisis de esfuerzo y deformación de la parte, incluyendo los efectos de la concentración de esfuerzos. Se concluye que el método desarrollado logra diseños rápidos, confiables, con aplicación en la industria y en enseñanza Resumen en inglés This paper describes an integrated computer-aided approach to the design of a gear reduction box involving modeling, simulation and automatic drawing. Powersim simulation software has been applied to develop a computer model of the mechanical structure. Special programs have been developed in order to produce two-dimensional drawings of the speed reducing assembly using AutoLisp language existing in AutoCAD . To obtain the optimal design of the parts, the results of the P (mas) owersim calculations can be transferred to Solid Work software for an automatic, three-dimensional design of the selected parts using a solid modeling method. Application of FEM software allows to create an automatic mesh and perform the analysis of the stress and deformation of the part including the effects of the stress concentration. It is concluded that the method developed achieves rapid, reliable designs, useful in both industry and teaching

Determination of greenhouse-specific aspects of ventilation using three-dimensional Computational Fluid Dynamics

Campen, J.B.; Bot, G.P.A.

The ventilation of a Spanish `parral¿ greenhouse was studied using three-dimensional computational fluid dynamics (CFD). The calculations were verified by experimental results from tracer gas measurements. Two types of roof openings have been considered; the rollup window configuration and the flap ...
