Simulation on Kinematics Law of Pedestrian in Vehicle/Pedestrian Contacting Phase

Based on the coupling of PC-Crash and embedded MADYMO, the multi-body system models of vehicle and pedestrian involved in a vehicle/pedestrian collision are established and validated. Main factors influencing on pedestrian kinematics in vehicle/pedestrian contacting phase are extensively analyzed; furthermore, the simulation test scheme is constructed from these factors. The kinematics laws of pedestrian such as motion posture, vehicle/pedestrian speed relationship and vehicle impact speed thresholds in vehicle/pedestrian contacting phase under different collision circumstances are in depth studied by selecting these main influencing factors as independent variables for simulation tests. The comparisons of simulation results with real world and staged vehicle/pedestrian collisions have verified a good harmony and consistency of kinematics law of pedestrian between them. The results in this paper will be of an important value in analysis of pedestrian kinematics in a vehicle/pedestrian collision.
