Abstract: Side airbag plays an important role in improving occupant protection in vehicle side imapct. The whole vehicle finite element (FE) model for side impact was developed with the software of PAM-CRASH by ESI Group. The FE model was validated by comparing the simulation and test results. The optimization method of side airbag parameters was discussed based on simulation. The leakage area, inflator gas flow rate and dimension of side airbag on a passenger car were optimized. Upon the improvement, the C-NCAP (China New Car Assessment Program) rating score of thorax on the car is improved from 0 to 1.8.

Key words:  vehicle side impact, side airbag, optimization design, simulation, software of PAM-CRASH
