A Study of Driver Airbag Shape Design with Process Integration

In this study, an integrated process was constructed to perform DOE analysis and find out effects of factors related to the driver airbag shape in NCAP frontal crash. 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 a driver NCAP frontal occupant crash model. An additional translation process was also integrated to the processes for the XML-based crash model that was modeled using MADYMO ver.6.1. iSIGHT was employed to the whole integration process parsing and the entire processes from driver airbag modeling to Design of Experiment (DOE) were performed automatically exchanging files between MADYMO server and iSIGHT server. From DOE analyses, improved results were achieved compared to the base design specification and factors that dominantly affect passive safety performance were found out.
