摘要： 车辆碰撞护栏是高速公路上常见的一类事故,主要有两种常用的车速分析方法,即法向弹性恢复系数法和切向摩擦系数法。但是由于高速公路上,车速较快,经常有车辆冲出道路,在此情况下,提出一种基于护栏变形能量的车速分析方法,用来计算车辆碰撞护栏时的最低速度,并通过实例进行了验证。

Abstract: Vehicle-barrier crash is a kind of accidents common on freeways. There are two methods for velocity analyzing, i.e. the method of normal elastic restitution coefficient and the method of tangential friction coefficient. As vehicles run very fast on freeways, they often rush out of roads when crashing barrier. In this case, a new method, which is based on the deformation energy of barrier, could be used for calculating the minimum collision velocity. The new method has been verified in practice.
