旋轮面上匀称刚体的滚动

ROLLING OF WELL BALANCED RIGID BODY ON CYCLOID-SURFACE

讨论旋轮面上匀称刚体的滚动规律,给出刚体从纯滚到滑滚的转折点和刚体离开曲面时的抛射点及其对应质心速度的计算公式。

Rolling law of well balanced rigid body on the cycloid-surface is discussed. The transition point from pure rolling to slide-rolling,Parabolic point when rigid body is away from the curved surface and the eguation of its cen-troidal velocity are described.
