本文由质点系对任一动点的动量矩定理导出了平面运动刚体相对于速度瞬心的动量矩定理,并就其实际应用价值和限制条件作了简单的论述.
In this paper, the momentum moment theorem of the plane motion rigid body with respect to the instantaneous center of gravity is derived from the point momentum theorem of any moving point in the particle system, and its practical application value and restriction conditions are briefly discussed.
