摘要
质点系以动点 O′为矩心的两种形式的动量矩定理,因不便于直接应用,所以教科书通常不能给出应用举例。本文对刚体平面运动进行了进一步推导,得出了有实用价值的定理表达式。文中还指出了动矩心选取的简明方法及应用举例。
It is usually not shown in textbooks how to apply the theorem of moment of momentum about a moving moment centre O′.The reference frame for it is large and it is perplexed for the choosing of moment centre O′.In this paper,a practical simple method and examples of choosing the moving moment center are presented.
