英文摘要：

Acquisition and analysis of vehicle crash data is the key to computer simulation. Based on a Pc-Crash software platform, a vehicle collision accident＇s data is analyzed by data identification, classification. And the weight sensitivity and the acquisition approaches are analyzed as well. Thus the method of vehicle collision simulation and reproduction are presented in this paper. This method is applied to the Pc-Crash platform to reproduce and simulate a real vehicle collision case. The results show that multi angle and multi path analysis of vehicle collision data can be used to study the cause of the accident more accurately and quickly.
