| Summary: | 碩士 === 元智大學 === 機械工程學系 === 100 === This study is to develop a systematic method to improve the die surface quality of high-strength automobile bumper, and to generate standard operating procedure for die design. In this study, a real bumper is first designed by an experience engineer with trial-and-error approach. Then, the technology of parametric optimization with AutoForm-Sigma are developed based on the traditional experience.
The technology of parametric optimization with AutoForm-Sigma takes the “performance analysis design.” This method uses the results of detail-Influence analysis to find the main influential parameters of surface quality. The surface defects can be improved efficiently by changing these parameters. Besides, the design parameters corresponded with the best objective function value in AutoForm-Sigma analysis could be used to get a better die surface. The results of real bumper case using above three methods show that the traditional design process takes forty design modifications to achieve the acceptable surface quality. The approach of parametric optimization with AutoForm-Sigma takes only eight modifications after the initial analysis runs.
