摘要
在对旋转与非旋转体接触摩擦引起振动机理分析的基础上，建立了非旋转体在接触摩擦力作用下的振动方程，并研究了其运动规律，发现非旋转体在滑动期的运动是一种以非旋转体的低阶固有振动为主的周期性粘滑振动，它与一般接触面之间由摩擦引起的粘滑振动不同，不论是粘着期还是滑动期，非旋转体都在振动，振动幅值与周期的大小不仅与静、动摩擦系数有关，而且与非旋转体的几何形状、物理参数。
Vibrating motion induced by friction between a revolute and non revolute body is analyzed. A periodic stick slip motion is found for the latter. It is different from the general stick slip vibration between two contacting bodies. The amplitude and period of stick slip vibration are related not only to the static and kinetic coefficient of friction but to the geometry, physical parameters, constraint of non revolute body and rotating speed of the revolute body as well.
