再论刚体在固定面上纯滚动时接触点的加速度

Velocity and Acceleration of Contact Point in the Plane Rotation upon Fixed Surfaces of Rigid

摘要: 应用点的速度合成定理和加速度合成定理，推导出刚体在固定曲面上作平面纯滚动时接触点的速度和加速度的计算公式. 该方法易于理解.

Abstract: Based on velocity composition theorem and acceleration composition theorem，while the rigid pure rolling upon fixed surfaces，calculated formulas on velocity and acceleration of contact point is deduced .The method is easy to understand.
