| 摘 要： | 用位移图，速度图，描述了摩擦自激振动，分析了伴生现象，建立了动力学模型和数学表达式，研究了该自激振动的机理及产生条件，引入运行均匀性系数，求解微分方程，推导出发生自激振动的临界速度公式，经与实践对照，两者有良好的一致性。 |

| Abstract: | Using the displacement scheme and velocity chart to describe the frictional selfexcited vibration (F.S.E.V.) and analyzing the accompanying phenomenon, a dynamic model and mathematic expression for F.S.E.V. are established. Its mechanism and its producing condition are investigated. Introduction of the movement uniform coeffiecient to solve the differential equation, the critical velocity of F.S.E.V. is deduced. The result is identical with practice. |
| Keywords: | lowspeed motion stability creep friction selfexcited vibration vibration of the machine tool |
