刚体平面运动对速度瞬心动量矩定理初探

ELEMENTARY RESEARCHES ON THE MOMENT OF MOMENTUM THEOREM ABOUT THE INSTANTANEOUS VELOCITY CENTER CONCERNING THE PLANE MOTION OF A RIGID BODY

本文讨论了刚体作平面运动时,动量矩定理的各种表达形式。特别是对速度瞬心的动量矩定理作了详细地探讨,并给出了具有简单形式的动量矩定理所应满足的条件。

This thesis analysed the various expressions to the moment of momentum theorem whena rigid body made a plane motion. In addition, it did particular researches on the moment ofmomentum theorem about the instantaneous velocity center and pointed out the necessaryconditions for the simplified form of the above theorem.
