Means and level of accident-handling are compelled to elevated to adapt the modern traffic development.This paper simulates the vehicle crash with nonlinear finite element analysis software. The feature of main parameter in the crash is shown in the paper. The relation of distortion and velocity is also given in the paper. The Expert-System was authorized to calculate and analyse the accident complexion. Much sense is important to the traffic-analysis. |
