| 摘 要： | 根据理论力学的知识，利用矢量法进行严密的数学推导，得出了作平面运动的任意刚体的惯性力系向任一点简化的结果，并由此结果进一步推导出了有对称平面的刚体在对称平面内作平面运动的惯性力系向其质心简化的结果，与目前出版物上的结果相一致。解决了多年来学习对平面运动的刚体的惯性力系简化结果的困惑，也为工程人员计算动力学问题提供了帮助。

| Abstract: | The inertia force system of an asymmetrically rigid body in plane motion is reduced to an equivalent system consisting of an inertia force and a inertia couple acting on an arbitrary point. And the results of resultants have been further discussed with respect to an asymmetrically rigid body and symmetrcally rigid body in Plane Motion. Also the results of resultants acting on the centroid of the rigid body have been derived. |
