Optimization of thorax-pelvic airbag for occupant safety in vehicle side impact
Paper i proceeding, 2012

Based on the C-NCAP side impact test results and component tests of a type of car, two typical type of pelvic-thorax airbag sub-models was developed using MADYMO and LS-DYNA software. They are single-chamber airbag with one inflator and dual-chamber airbag with two inflators. Based on the analysis of parameters of the single-chamber airbag, the factors that influence the dual-chamber airbag are determined. The protection performance of those side airbags were investigated using orthogonal experiment design (OED) and comprehensive equilibrium methods. The models with better performance were found and factors that influence the two different side airbag were determined. The injury of the dummy decreased dramatically in side impact and met the C-NCAP requirement.
