碰撞阻尼

根据弹性体碰撞理论和结构模态分析，提出一种简便方法识别两弹性结构的碰撞恢复系数和碰撞速度，进而可确定碰撞阻尼.该方法及后继的碰撞振动分析涉及到结构模态截断。

On the basis of collision model of two elastic bodies and modal analysis of elastic structures , a simple approach is proposed to identify the restitution coefficient and impact velocity of two elastic structures such that the collision damping can be determined .
