In order to obtain the accuracy of vehicle parameters and occupant injury information after collision, and reduce the high cost of the sample vehicle crash test and the uncertain factors in the collision process, build rigid body model and multi-rigid body model by PC-Crash platform of traffic accident reconstruction software. Set the parameters and initial motion state of the model, and carry out the simulation and reconstruction of the traffic accident collision, which can obtain instantaneous motion state parameters of the collision vehicle and occupant. To simulate and demonstrate the process of the traffic accident, comparing the demonstration results with the actual traffic accidents, and the reduction rate of the real motion pattern is more than 95%,so that the effectiveness of this method is verified. It provides a reference for the better use of PC-Crash software to realize the simulation analysis of occupant's frontal injury, and provides a theoretical basis for accident treatment.
