摘　　要：本文运用几何方法找到了计算刚体平面运动瞬心加速度的一般公式,并在此基础上导出了对瞬心的动量矩定理,从而使瞬心法成为求解刚体平面运动的完整、有效的方法.This paper gives a general formula for the acceleration of instantaneous cen-tre of (?)gid body's rotation in the planar motion and the theorem of angular momentumof rigid body was worked out,with the geometrical method.Therefore,they make themethod of instantaneous centre into a complete and effective method to resolve someproblems about planar motion of rigid body.

关 键 词：刚体平面运动 瞬心 动量矩定理
