对本体极迹和空间极迹方程推导的讨论

Discussing on Derivation of Body Centroide and Herpolhode Equation

本文对某些理论力学教材中速度瞬心的本体极迹和空间极迹方程的推导提出异议,给出合理的解释,同时介绍了一种更简洁的求解方法。

In this paper, some different views and explanations on the derivation method of body centroide and herpolhode equation with speed-center in some theoretical mechanics textbook are proposed. Meanwhile, one easer way to solve the equations is introduced.
