Analyzing on post-impact equivalent velocity of the vehicle side-slipping and rotating

摘要

Pre-impact speed of the vehicle in the road traffic accident is the important index of dealing with traffic accidents responsibility. We investigate the relation between the road adhesion coefficient and the vehicle side-sliding angle, to constructing adhesion coefficient ellipse equation and then building the precise mathematical model, application on integral principle restructure solving post-impact equivalent velocity mathematical model building. In terms of actual case comparative analysis, the proposed method of in this paper improves 8% for calculation post-impact velocity of the vehicle than the traditional method in the traffic accident. Therefore the calculated method is great significance for guarantee judicial fairness.
