Abstract: Objective To reconstruct the course of vehicle collision, so that to provide the reference for forensic identification and disposal of traffic accidents. Methods Through analyzing evidences left both on passengers and vehicles, technique of momentum impulse combined with multi-dynamics was applied to simulate the motion and injury of passengers as well as the track of vehicles. Results Model of computer stimulation perfectly reconstructed phases of the traffic collision, which coincide with details found by forensic investigation. Conclusion Computer stimulation is helpful and feasible for forensic identification in traffic accidents.
