A hull structure is constituted by thin panels, and reinforced longitudinally and laterally by stiffened members to increase the effectiveness of the structure. In order to attain findings on buckling and plastic collapse behavior of stiffened plates, this paper describes analysis of elasto-plastic large deflection by using the finite element method on thin stiffened plates having flat-bars and angle-bars. The analysis includes the case of an aspect ratio being 5.0 and the case to consider welding residual stress. Considerations were given on cross sectional shape, panel aspect ratio and effects of initial welding imperfections against the buckling and plastic collapse behavior of the stiffened plates. The angle-bars tend to cause secondary buckling more easily because it has greater bending and twisting rigidity, and stronger constraint against deflection than the flat-bars. When the aspect ratio is larger and the span is longer, the ultimate strength declines, and the withstand power after the ultimate strength decreases rapidly. Existence of the residual stress tends to make the secondary buckling occur more easily. The secondary buckling affects little the withstand power after the ultimate strength. 3 refs., 7 figs., 1 tab.

NO{sub x} emission was remarkably reduced by PREDIC (PREmixed lean DIesel Combustion) system in which fuel was injected at very early stage of compression stroke and the major part of the fuel is considered to be burned with self-ignition of premixed charge around TDC. However PREDIC system had some problems, a restriction of a high load operation was one of these problems. In order to investigate the combustion characteristics of PREDIC at the richer operation limit, a test engine was operated with gaseous fuel-air mixture where less heterogeneous mixture can be formed than that of conventional diesel engines. A steep pressure rise or the abrupt increase in NO{sub x} emission determined the richer operation limit. This was at 2 to 2.4 of excess air ratio. Supercharging operation enabled the high load operation more than 2.4 of excess air ratio. (author)

Simultaneous reduction of NO{sub x} and smoke under high load conditions could be obtained by MULDIC (MULtiple stage DIesel Combustion) where mixture was made stratified before ignition. In this investigation of the basic characteristics of MULDIC, gaseous fuels (DME, Propane) were charged into the intake air which led to the creation of homogeneous lean mixture, and liquid fuel was injected into the cylinder and made rich mixture. The results of the engine test showed that NO{sub x} emissions could be reduced to less than 100 ppm and smoke emissions were also maintained 0 FSN even at higher loads. Moreover, homogeneous rich mixture test results showed that low smoke combustion could be obtained under equivalence ratio of 1.6. In MULDIC, increasing the ignition delay period of injected fuel, soot formation rate was decreased, because over rich region was avoided. (author)

Dynamic force on blades in a large wind mill changes with rotational speed for various reasons, such as wind shear that causes vertical distribution of wind velocity or titling angle. Therefore, a 2-blade system on a teetered hub is a practical selection for the coned, down-wind type. Use of teetered axis greatly reduces bending moment in the flap direction and that at the axis of rotation. An attempt was made to understand dynamic loads by inertial force resulting from oscillation of the blade rotating on the teetered axis, and thereby to avoid them. The in-plane load can be diminished to zero when the teetered axis is coincided with the center of gravity, but generally cannot be avoided when the blade is strained significantly, except it is operated at the rated condition. The in-plane load and bending moment can be avoided, when rotational freedom is given around the y axis. Dynamic load on a down-wind rotor can be avoided by use of universal joint. 3 refs., 6 figs.

By injecting fuel at the very early stage of compression stroke and thus creating homogeneous lean mixture before ignition, (PREDIC ; PREmixed lean DIesel Combustion), simultaneous reduction of NO{sub x} and smoke was obtained. However, since increasing the mixture equivalence ratio cause knocking, it was difficult to operate at higher load conditions. In this study, in order to reduce combustion rate at high load conditions in a premixed compression ignition engine, multiple stage injection method and EGR were combined, and heterogeneous mixture was made before ignition. The engine test results showed that NO{sub x} emissions could be reduced to less than 50 ppm, without knocking even at full load conditions. In addition, smoke emissions were also maintained below invisible level. It can be understood that the premixing of fuel was advanced, smoke was reduced, and EGR rate was increased, resulting lower heat release rate and NO{sub x} emissions. (author)

The deformation mechanisms of submerged shell-like lattice structures with membrane are in principle of a non-conservative nature since the follower type hydrostatic pressure. In the region of large deformations, especially in the case of geometrically deep shell-like lattice structures, the system could be much more accurately defined in a mono-clinically convected coordinate description than the conventional spatial description. Also, a complete analysis of a non-conservative system requires a criterion since the system can have multiple ranges of stability and instability involving buckling and snapping. This paper presents the development of the governing equations for the finite deformations of shell-like lattices defined in a mono-clincally convected coordinate description and applies the same to different cases of lattice deformations. The validity of the formulations is verified for finite deformation. The examples of some geometrically special shell-like lattice structures are presented as well to show the feasibility of the present formulation. 5 refs., 11 figs.

This paper describes the deformation and dynamic stability of circular arch subjected to follower forces in a submerged membrane type marine structure reinforced by arch frames. Governing equations for finite deformations of the circular arch subjected to follower forces are introduced using an embedded curve coordinate, which are formulated by applying Galerkin method. In addition, equations of motion due to small disturbances under given condition of loading are introduced. Based on these equations, dynamic stability of the arch is analyzed by means of Runnge-Kutta-Gill method, to clarify the relationship between disturbances and instability regions and the resulting phenomena. Near the boundary regions of stability, both amplitude and cycle of deformation are greatly affected by the amplitude of disturbances. The dynamic instability is governed by the inverse symmetry primary mode with minimum characteristic frequency which is specific for the circular arch. The dynamic stability has high parameter dependency, and the instability regions have a complicated shapes. Although flattened arch has a smaller static critical load, it provides the dynamic stability against the disturbance. 5 refs., 10 figs.

This paper discusses the preparation factors and curing conditions of superhigh-strength mortar, and explains a method of manufacturing superhigh-strength mortar having still higher strength and its superhigh strength generating mechanism. A recommended cement material for the superhigh-strength mortar is a Portland cement mixed with a high-purity silica at 20% and silica fume at 20%. This was made to a water-cement material ratio of 15% and fine aggregate cement material ratio of 1.06, cured in an autoclave, and further heat-cured at 200{degree}C for one day to obtain a superhigh-strength mortar. The compression and bending strengths reach 2,200 kgf/cm{sup 2} and 180 kgf/cm{sup 2} respectively when used with silica sand, and 3000 kgf/cm{sup 2} and 220 kgf/cm{sup 2} or more when used with stainless steel grits. The heat curing at 200{degree}C for a day increases remarkably the compression strength of the superhigh-strength mortar regardless of the curing conditions before the heat curing. 7 refs., 11 figs., 1 tab.

The compressed air energy storage gas turbine power generation system is paid attetion to as a load levelling power source in view of the recent increase in electric power demand. The paper describes features, cavern construction technology, economy and future expansion of the system. In this system compressed air made by use of cheap night-time electric power is stored in underground spaces or underwater facilities. Burning the fuel together with this compressed air in the daytime, the gas turbine power generation is conducted. Several examples overseas of this system are reported including a 290,000KW class in Germany. A key technology of the system is how safely and cheaply a large amount of hih-pressure air can be stored. In Europe and America, caverns of hundreds of thousand m {sub 3} are constructed in the rock salt cavern which can be excavated by a water jet. In consideration of storing it in rock beds in Japan where there are no rock salt caverns, NEDO started 1990 a 9-year construction plan of a 35,000 KW class pilot plant at Kamisunagawa, Hokkaido. 2 refs., 5 figs., 1 tab.

Compressed air energy storage (CAES) has been studied as a promising storage system which has a good possibility of being put to practical use. Construction of the storage facility is required for CAES. For an economical construction of a storage facility, it is necessary to construct a storage facility by excavating, from the ground surface, a cavity in the ground. There is no case in Japan where rock storage is adopted with several tens of atmospheric pressure which is necessary for CAES. If highly pressurized air can be stored by the water sealing method, it is a very economical method in the case with hard rocks. As the first stem to verify the effectivity of the water sealing system, a water sealing experiment is performed in a boring hole. It is confirmed that water sealing can be possible up to about 40 atmospheres, and it is found that the resistivity, open joint distribution and coefficient of permeability of rocks have correlation as an investigating method for potential cracks in rocks and that resistivity tomography is effective for the investigation of cracks in rocks. 9 ref., 23 figs., 6 tabs.

Single fuel operation with diesel fuel has been tried experimentally for the Homogeneous Charge Diesel Combustion method (HCDC). The higher the pre-mixed fuel ratio, the lower the emissions. But diesel knock due to early self ignition may be occurred under high pre-mixed fuel ratio conditions and consequently the maximum pre-mixed fuel ratio is restricted by these knock limits. Full load operations with higher pre-mixed fuel ratio can be possible with a supercharging which improve the knock limits and emissions. 8 refs., 12 figs.

A free piston shock tunnel has been intensively used as a hypersonic flow ground test facility and its characteristics depend sensitively upon the piston motion in its compression tube. The continuous measurement of the piston motion in its compression tube was studied in an analogue facility in which a piston motion in a 50mm dia. and 2000mm long compression tube was measured continuously and accurately from its start to the collision with bumper section. To achieve it a velocity interferometer was developed particularly to measure the piston speed in it. Then piston motions were successfully measured and result agreed very well with numerical result.

As lean burn of compressed natural gas (CNG) is applied to conventional gasoline engines, a combustion period largely increases, resulting in large combustion fluctuation and low thermal efficiency. Heterogeneous spacial air/fuel ratios also have an effect on combustion in lean burn area. By preparing a pre-chamber for a combustion chamber of high- compression ratio CNG pre-mixing SI engines to utilize premixture turbulence, rapid flame propagation is obtained in lean burn area, resulting high combustion performance. Furthermore, study was made on improvement of combustion performance in lean burn area under various compression ratios, intake pressures, pre-chamber shapes and EGR ratios. As a result, lean burn operation at high intake pressure by supercharging showed possible improvement of a thermal efficiency and expansion of inflammable limits. Higher thermal efficiency in lean burn area was also obtained by using higher compression ratios considering heat loss. Although EGR was effective in controlling NOx formed in lean burn area, strict control of both air excess rate and EGR rate was required to prevent lower thermal efficiency. 2 refs., 8 figs., 1 tab.
