| 摘 要： | 本文建立了由刀架弹性子系统、工件弹性子系统在非线性动态切削力耦合下的多自由度非线性系统的速度型切削颤振理论模型，通过数值模拟显示，此系统存在内共振现象，从而解释了速度型切削颤振发生的振动机理。为解决切削颤振问题提供了一种新的技术途径。

| Abstract: | By help of nonlinear vibration theory, a mechanical model is presented to analyze the speed type chatter of multi degree of freedom nonlinear vibration system. In the model, the elastic subsystem of machine tool frame is coupled with the elastic subsystem of element burring cut by means of nonlinear dynamic cutting force. Numerical simulation shows that there exists the internal resonance phenomenon. The vibration mechanism of the speed type chatter is established and a new way to prevent chatter is obtained. |
