In this study, an occupant restraint system model of a production SUV developed in MADYMO software was used for crash simulations. Component tests were conducted to obtain the parameters of seatbelt and seat. Parameters of airbag were obtained by tank tests and the airbag model was validated by headform drop tests. The occupant restraint system model was validated against results from real vehicle crash tests. Robust design method was adopted for sensitivity analysis and system optimization. Two parameters, spool effect of the seatbelt and mass flow of the airbag, were studied to improve the occupant protection. Better protection performance has been obtained using optimized parameters, and the robustness of the optimized result was proved by robustness assessment.
