The nonlinear finite element structural analysis software was used to simulate the frontal collision of many cars. The basic laws of the characteristic parameters such as displacement, velocity, acceleration and energy are given. It is pointed out that the relationship between the deformation and speed of frontal collision of vehicles is parabolic equation and car classification method, and its practical equation is given. Applying it to traffic accident analysis provides a theoretical basis for the identification of liability for traffic accidents
