In the research, the study of car impact test and numerical simulation method are both used. Based on works that have done, an impact model containing car model, dummy and restriction system model was built. According to national regulation, different types of impacts were simulated. The fuel cell auto's impact safety was analyzed, and the injury criterion for occupant can be read out directly by simulation data. The main research content of this project is to set up the fuel cell auto's frontal impact model, side-impact model, rear-impact model and the whole frontal impact model, which contains car model, dummy, restriction system model and so on, and calculating these models.
