Computer Simulation of the Frontal Crash of the Integrated Car-occupant Restraint System Model

The simulation of the crashworthiness of the car and the occupant behavior was often realized in succession. In this paper, the coupling models were considered. The complete finite element models of a passenger car and the occupant restraint system including a 50th percentile Hybrid Ⅲ dummy, the seatbelt subsystem and a driver side airbag, were presented. According to the CMVDR 294, the frontal crash into a rigid wall of the car at about 48km/h was successfully simulated and the results were found to be consistent and in good agreement with the crash test data. The analysis and comparison of different restraint situations were also given.
