基于变形能的汽车碰撞分析新模型

A New Vehicle Collision Model Based On Deformation Energy

提出了基于变形能的汽车碰撞分析新模型,以动量守恒为基础,根据恢复系数与碰撞过程中的能量损失,建立补充方程来进行碰撞过程的分析计算。该模型分析过程简单可靠,可以方便地应用于碰撞过程的研究。

In this paper, a new vehicle collision model based on deformation energyis presented, through establishingtwo supplement equations based on restitute cOefficient and energy loss, and combining the law of conservation of momentum, the speed before collision can be calculated. The result shows that, the model analysis is easy and credibility to analyze the collision process.
