This paper describes in detail the extension of the discrete kinetic time forward PC-Crash simulation program to deal with multi-body systems. As one application of this model pedestrians have been modeled. During the generation of this pedestrian model special interest has been focused on a realistic movement of the pedestrian and a short calculation time. The pedestrian model shows to be a good tool to analyze the movement of the pedestrian regarding its post impact kinematics and contact locations on the vehicles and the ground. In addition, specific contact locations on the vehicle can be correlated with the movement of the pedestrian and damage locations on the vehicle. For the validation of this model, several crash tests have been performed and will be done. The paper also describes the results of some crash tests and a comparison of the simulation results. A good agreement between crash tests and simulation results was found. For these crash tests different typical shapes of the front hood of modern cars have been used to study the influence on the movement of the pedestrian during and after the impact.
