并对夹持点的接触速度，加速度及其跃度进行了分析，从中找出了尽量减小接触冲击的有效途径。

The touch velocity, acceleration and jerk of clamping points have been analysed. From these analysis results an effective way has been found in order to decrease the touch impact as far as possible.

对于二维碰撞，可以根据车辆的碰撞位置和停止位置，反推计算出车辆碰撞后的分离速度和碰撞前的接触速度。

For collinear collision, the preceding collision velocity and post collision velocity are calculated on the basis of the impact locality and stop locality of collision vehicle.
