The kinetic energy loss calculated mode of collision for the two-rigid-body system with sliding friction

摘要

摘要: 讨论的是一般运动刚体在含有滑动摩擦的情况下的两体碰撞．首先根据欧勒动力学方程和质心运动定理导出了在碰撞的两个阶段二碰撞点沿公法线和公切线的相对速度的变化量, 其次利用动量定理导出了系统动能的损失与二碰撞点速度的关系, 最后根据这两个结论导出了系统动能损失的计算公式, 并给出所得结论成立的条件．

Abstract: The kinetic energy loss calculated mode of collision for the two-rigid-body system with sliding friction is derived.
