关于瞬心作为基点的讨论

Instantaneous Center as Base in the Rotation of Rigid Body

讨论刚体转动中以瞬心作为选定中心的合理性 ,并通过分析刚体在平面、斜面以及曲面上做纯滚动运动的三种情况 。

The author discussed the rationality of instantaneous center as base, and analysed the pure rotation of rigid body on the plane, slant and curve surface respectively, finally discussed the methods of analyzing the rotation of rigid body with instantaneous center as base and the character of inertial moment.
