Abstract

The progress of vehicle collision can be broken into three stages: pre-collision, collision and post-collision. Although the direct collision lasts very little time, it is one of the most important stages of the whole process. On the basis of Momentum Conservation, Energy Conservation and improved Coefficient of Elastic Recovery, using Newtonian Mechanics, the paper constructs dynamics model for vehicles' two-dimensional collisions, which can be used to calculate the velocities at the moments of before and after the collision. The paper uses the Software of PC-Crash as a comparative study, the results of which show that the proposed models are suitable for the analysis of collisions involving only two cars without second collision.
