圆轮在固定面纯滚动时加速度瞬心的轨迹分析

The trajectory analysis of instantaneous center acceleration of the round of pure rolling on the fixed surface

推导了圆轮在固定面上纯滚动时其上任意点的加速度计算公式,数值分析了圆轮在固定面纯滚动时加速度瞬心轨迹的分布规律,可加深理解圆轮纯滚动时的运动规律,为平面运动图形上点的加速度分析提供了另一种有效方法.

The paper focuses on the deduction of the acceleration formula of any point at the round of pure roll- ing on the fixed surface. The characteristics of tracks of the acceleration instantaneous center at the wheel pure roll- ing on a fixed surface are analyzed, and the movement of the wheels pure rolling is more deeply understood. An ef- fective method of point acceleration of plane motion graphics is provided.
