关于“对速度瞬心动量矩定理”讨论

RESEARCH ON THEOREM OF THE CHANGE IN ANGULAR MOMENTUM

当刚体作平面运动时,可采用“对速度瞬心动量矩定理”J_Aε+Mωpp′=∑m_A(■)。对这个定理的证明方法已有几种了,本文是应用达朗伯原理加以证明,并对该定理可取J_Aε=∑m_A(■)的条件进行全面讨论。

when plane motion of rigid body To Abstract use for the instantaneon centre of zero velocity is possible. That is J_(Aε)+MωPP′=∑mA(■), that has show nin several ways. which should be tested by D' AKEMBERT' Sprinciple, en This te xfwnich may take J_(Aε)=∑mA(■) as coudtion and thewholly discussion.
