碰撞刚度系数及其在交通事故分析中的作用

Collision Stiffness Coefficient and Action in Traffic Accidents Analysis

在介绍了碰撞刚度系数概念的基础上，首次用实车碰撞试验数据导出了我国汽车的刚度系数，并用实际发生的交通事故对刚度系数的精度进行了验证．证明通过碰撞试验所获得的刚度系数应用于对交通事故的分析中是可行的．提出了应将“如何用有限的刚度系数来推算各种事故中车速的变化量”作为今后研究的重点的观点．

On the base of introducing conception of collision stiffness coefficient,the collision stiffness coefficient of domestic automobil e are calculated using the date from full size vehicles collision test s for the first time.The precision of the stiffness coefficient is tes ted and verified by actual traffic accident.It is feasible that the st iffness coefficient obtained by the collision tests are applied in tra ffic accident analysis.A viewpoint is set forth that the collision spe ed in various kinds collision can be calculated using stiffness coeffi cient should be regarded as researching focal point.
