Abstract: Taking a car as the object, a vehicle finite element model including the occupant restraint system was established. In LS-DYNA environment, the whole model was divided into 360, 000 shell elements for numerical simulation of the front crashing process. The energy transfer and dissipation, the energy absorption effect of the main structure and the deformation damage index of the driving dummy were analyzed. The comparison between the simulation and the crashing test confirms the effectiveness of the finite element model including the occupant restraint system. The proposed car collision model including the occupant restraint system and the computer simulation method reflect the status and the results of the real vehicle crash, which have some practical value in engineering application.
