According to the Chinese feature parameters, sixteen-rigid body has been built in this paper. Spring-damp joints are used in the important parts of pedestrian. Vehicle model and impact model is built using the ADAMS software. Kinetic and dynamic characteristics between pedestrian and vehicle are studied in this paper. And during the progress of impact acceleration of pedestrian's main body parts and impact force of head under different pedestrian-vehicle velocity angles are studied. This method of testing can be used in accidents to analyze pedestrian's body injury.
