,which has been proved to have a good biofidelity,a car-pedestrian impact simulation model was developed.

A series of computer simulations had been done,which included the simulations of the legform impactor tests using the legform impactor model in MADYMO software and the simulations of the car-pedestrian impacts using the pedestrian model with good biofidelity.

Kinematic characteristic of elastic-plastic debris behavior in vehicle collision;

Dynamics analysis on motorists during vehicle collision accidents;

Research on the calculation models of vehicle collision for analyzing traffic accidents;

Vehicle impact test is one of the mandatory tests for vehicle design regulations in China.

Nonlinear and non-stability car impact signal processing method is strdied,and time-frequency for multi-resolution is analyzed.

Some traditional international pedestrian injury formulas were simply improved and pedestrian injury was analyzed on the basis of introducing the characteristics between pedestrian and car impact and the relevant measured parameters.
