摘要: 用矢量分析的方法求出刚体在固定曲面上作纯滚动时接触点、即速度瞬心的加速度的表示式.

关键词: 刚体运动学, 纯滚动, 加速度

Abstract: Based on the vector analysis method,the acceleration of the contact point,also the instantaneous center of rotation for a rigid body that rolls without sliding on the fixed surface,is obtained.

Key words: kinematics of a rigid body, rolling without sliding, acceleration
