摘要
以旋转体和端部有集中质量的弹性阶梯形悬臂梁系统为研究对象。在旋转圆盘以匀角速度转动的情况下,根据Lagrange方程,导出了系统的运动微分方程。从理论上计算和分析了旋转摩擦诱发梁端质量块的粘滑运动规律,并对影响粘滑运动的主要因素进行了讨论。
The system constituted by the rotary body and the elastic stepped cantilevered beam with a concentrated mass at the free end is investigated. In the case of the disk rotating at the uniform angular speed, the differential equation of motion of the system is derived based on the Lagrange equation. The stick-slip motion law of the mass blocks induced by rotary friction at the beam end is calculated and analyzed theoretically, and the influencing factors upon the stick-slip motion are discussed.
