This work deals with the development of the analytical method in order to predict the stability chart of regenerative chatter in spite of the change of the mechanical transfer characteristics, the cutting condition and the cutting stiffness. The stability chart of regenerative chatter was predicted by the proposed analytical method with the hybrid model composed of the tool and spindle system modeled by continuum model and the workpiece model. It was confirmed that the stability chart of regenerative chatter predicted by the eigenvalue analysis coincided well with the experimental result.

这项工作涉及的分析方法的发展，以预测再生颤振的稳定性图表，尽管机械传递特性，切削条件和切削刚度的变化。采用由连续介质模型和工件模型组成的刀具-主轴系统混合模型，利用所提出的解析方法预测了再生颤振的稳定性图。结果表明，特征值分析预测的再生颤振稳定性图与实验结果吻合较好。
