摘要
分析了瞬心的加速度特性，建立了刚体平面纯滚动的轨迹方程。指出瞬心加速度正交于瞬心线。据此，不仅能将圆盘纯滚动运动分析纳入普通的杆系几何法，而且可简化任意轮廓的刚体纯滚动的运动分析过程。
The characteristics of the acceleration of the instantaneous velocity center(IVC) were presented, and the trajectory equation for pure rolling of rigid body (PRORB) was developed. The conclusion is that the acceleration of IVC is orthogonal to velocity centrode.In the light of this, not only the geometric motion analysis method for PRORB can be included in normal analysls for rod-type system motion, but also its computational process can be simplified.
