碰撞问题的速度矩阵表达和能量损失及传递率分析

Analysis on Velocity Matrix Representation,Energy Loss and Transfer Rate of Impact Issue

以两体碰撞为例,对碰撞前后的速度关系利用矩阵作了简明表达.全面分析了碰撞前后的能量组成及关系,阐述了资用能的物理意义,求出了能量损失、能量传递率等表达式.本文的分析方法也可推广到多体碰撞问题中去.

Taking the two-- body collision as an example, the relation of bodies velocity between before and after collision is concisely expressed in matrix form. The component parts of collision energy of the bodies and their relations between before and after collision are analyzed thoroughly and the physical meaning of available energy is elaborated, furthermore, expressions of the loss of energy and the energy transfer rate are derived. The analysis method described here may be adopted for many- body collisions issues.
