三质点弹簧系统的运动分析

Analysis on movement of the spring system with three particles

分析了一个由三质点和弹簧构成的系统的运动问题,给出了三质点质量满足不同关系时各质点的运动微分方程,求出了运动微分方程的解析解,并由此讨论了各质点的运动规律.

The spring system with three mass points is studied. The differential equations of three mass points are derived for different mass relations between them, and their analytic solutions are obtained, by which the movement rule of three mass points are discussed.
