一起交通事故中车辆碰撞速度的分析计算

Analysis and calculation of vehicle collision speed in a traffic accident

分析交通事故发生的原因,速度则是关键性的因素。汽车碰撞过程本质上就是车速剧烈变化的过程。如何正确推算出事故发生瞬间的碰撞车速,为交通事故处理提供间接的理论依据。本文正是基于一起交通事故中,两车碰撞后产生的塑性变形量和滑移距离,运用运动学理论,引用典型事故速度计算公式,推算出两车碰撞前的速度。

Speed is the key factor in analyzing the reasons of traffic accidents.The automotive collision is essentially dramatic change process of speed.The accurate calculation of the moment-speed of collision accidents provides indirect theoretical evidence for handling traffic accidents.Based on plastic deformation and sliding distance in a traffic accident,this article calculates the speed of the two vehicles before the collision by using kinetic theory and citing the typical accident rate formula.
