운전석 에어백 형상 최적화에 관한 연구

In this study, an optimization process was integrated to determine the optimum design variable values related to the driver airbag shape. A finite element driver airbag was modeled using BAGGEN, one of the MADYMO ver.5.4.1 utilities. The airbag modeling process was integrated with an NCAP frontal occupant crash model. An additional translation process was also integrated to the processes for the XML-based crash model that was constructed using MADYMO ver.6. 1. iSIGHT was employed to the whole integration process parsing and the entire processes from driver airbag modeling to optimization analysis were performed automatically exchanging files between MADYMO server and iSIGHT server. The improved results compared to the base design specification were achieved from Design of Experiment(DOE) and optimization.
