摘要
本文应用达朗伯原理,证明在刚体作平面运动时,以任一动点为矩心的动量矩方程的一般表达形式,并通过讨论给出采用一些特殊点作为矩心时,其动量矩方程的简捷表达形式和应用条件。
In this paper,general expression formulas of equations of moment of momentum about any of its moving points is proved when a rigid body is in plane motion by using of D'Alember's Principle.Then simple expression formulas and application conditions of equation of moment of momentum about some special points taken as center of moment axe discussed and given.
