        Thin-film shape technology is recognized for its core technology to enhance the technology of LCD, PDP, semiconductor manufacturing processes, hard disks and optical disks, and is widely used to form coated thin films of products. In addition, resistance(electron beam filament) technology for heating is used to manufacture filament for ion implants used in semiconductor manufacturing processes. By establishing an electronic beam filament production system and developing seven specifications of electronic beam filament, it is contributing to improving trade dynamics and increasing exports to Japan through localized media of theoretical imports to domestic companies. In this study, CAE analysis was performed after setting electron beam filament specification and development objectives, facilities and fabrication for electron beam filament production, electron beam filament JIG & fixture design and fabrication followed by electron beam filament prototype. Then, the automation and complete inspection equipment of the previously developed electronic beam filament manufacturing facilities was developed and researched to mass-produce them, to analyze and modify prototypes, design and manufacture automation facilities, and finally, to design and manufacture the complete inspection equipment. In this paper, mainly electron beam filament specification analysis and development objectives and CAE analysis were dealted with.

        The vehicle weight and alternative light materials development like aluminum alloys are hot issues around the world. In order to obtain the goal of the weight reduction of automobiles, the researches about lighter and stronger suspension links have been studies without sacrificing the safety of automotive components. Therefore, in present study, the structure analysis of the torque strut links made by aluminum alloys (A356) was performed by using CAE (computer aided engineering) to investigate the light weight design process from the reference of the rear suspension torque strut link which was made by STKM11A steel and was already proven in the commercial market. Especially, the simulated maximum von Mises stresses after strength analysis were normalized as fatigue limit and these were converted to the WF (weight factor) of the same type as the fatigue safety factor suggested and named like that in present study. From these, it was suggested that the fatigue properties of the torque strut could be simply predicted only from this static CAE simulation.

        This study is making a product for the development of a process worm wheel of making a shape for gear for worm wheel without hobbing manufacturing process. Because of removing a hobbing process, plastic worm wheel for increased productivity and equivalent quality is produced in this molding. As the result, CAE manufacturing process for a EPS worm wheel of small and middle stage cars and hybrid vehicle is developed. Especially, the considerations for analysis results of worm wheel are as follows. the first, CAE analysis for worm wheel of first stage is considered. the second, CAE analysis for boss is considered. the third, CAE analysis for gear module strength of first stage is considered. Finally, the redesign of product drawings for troubled-considered in first stage try-out is considered in EPS worm wheel.

        Power steering gear is the part of an automobile. That converts circular movement of steering wheel into lateral movement of rack for changing driving direction. Recently power steering gear gets more common. A Korean company manufactures a speed sensitive power steering gear, which provides variable steering feel depending on speed of the car. However, the Broens company in Australia produces and exports the test equipments for manufacturing power steering valves. Some Korean companies import the test equipments from Broens and the maintenance cost gets increasing. The purpose of this study is development of the valve balance tester to measure the valve torque of the power steering gear. This study designed and manufactured a chuck and a jig of the valve balance tester to take hold of the power steering valve using CAE analysis.

        Crack generation during die compaction and distortion during sintering have been critical problems for the conventional pressing and sintering process. Until now, trial and error approach with engineers' industrial experiences has been only solution to protect the crack generation and distortion. However, with complexity in shape and process it is very difficult to design process conditions without CAE analysis. We developed the exclusive CAE software (PMsolver/Compaction) for die compaction process. The accuracy of PMsolver is verified by comparing the finite element simulation results with experimental results. The simplified procedures to find material properties are proposed and verified with iron based powder and tungsten carbide powder. Based on the accurate simulation result by PMsolver, the optimal process conditions are designed to get uniform density distribution in a powder compact after die compaction process by using a derivative based optimization scheme. In addition, the effect of non-uniform density distribution in a powder compact on distortion during sintering is shown in case of the fabrication of tungsten carbide insert.

        In this study, the soil-structure interaction impact of a 3-hinge Concrete Modular Underground Arch (CMUA) is simulated using Abaqus/CAE. The results indicate that Abaqus/CAE is an effective tool for seismic simulation of the CMUA. Besides, the structural damage under the earthquake impact can occur locally on lining structure or its surrounding at the soils that is influenced significantly by the interaction and contact between structural parts as well as linkages of segments.
