摘　　要：在颤振的各种激振机制中,再生效应被认为是最直接、最主要的激振机制。从切削加工的动力学模型入手,研究主轴转速对颤振的影响,发现在主轴转速较低时,系统振动有节拍现象和谐波振动;当主轴处于高速旋转时,体系振动状态趋于无序。In all kinds of the chatter excitation mechanisms, the regenerative chatter is considered to be the most directly and important exciting mechanisms. Based on the kinetic model of cutting, the relationship between the speed of spindle and chatter has been analyzed,finding that rhythmic and harmonic vibration phenomena appears when the spindle speed is low, and at high spindle speed, the system vibration tends to disorder.
