Abstract

In order to optimize occupant restraint system and improve the safety of occupant, the effect of occupant restraint system of microbus on head and chest injury is studied. The numerical simulation model is built by MADYMO software according to the frontal crash regulations. The numerical occupant restraint system model of microbus is composed of microbus body, occupant restraint system, and dummy. Based on the calculating results of MADYMO, Head Injury Criterion (HIC), and the amount of chest compression, the safety elongation is 13%, and the limited stress is 4.5 kN. Compared with the occupant restraint system of Microbus before optimization, the WIC, HIC, and chest compression decreased of optimized occupant restraint system decreased by 21.2, 30.8, 1% respectively.
