汽车碰撞事故的速度分析

Velocity analysis of vehicle cracking accident

通过对交通事故中汽车的碰撞问题的简化 ,运用动量守恒定理和能量守恒定律着重研究了正面碰撞、追尾碰撞和侧面碰撞三种情况下 ,汽车碰撞前动量和速度的求解方法 ,为交通事故模拟和再现提供了一种更为实用的方法 ,并为科学处理交通事故、明确事故责任提供了重要参考。

The model of vehicle cracking in the traffic accident is simplified. And the solving methods of motivations and velocities before cracking are studied by using motion and energy rules from front cracking,rear cracking,and side cracking. These can be reference for treating the traffic accident sciencetificly and confirming the accidental responsibility.
