摘　　要：基于再生颤振机理,研究和建立动态铣削加工振动系统的闭环控制系统,以及其传递函数模型.应用模态分析理论,研究加工振动系统的复模态振型,实现其传递函数矩阵模态参数,包括模态质量、模态阻尼和模态刚度等的辨识,为动态铣削加工振动的预估和有效控制奠定理论基础.A closed-loop control system and its transfer function models of dynamic milling process are established and studied based on regenerative chatter theory. Research on plural modal models of milling vibration system is conducted with modal analysis theory. Modal parameters of transfer function models of the vibration system, including modal mass, modal damp and modal rigidity are identified. These results will be important to estimate and control effectively on vibration in dynamic milling process.
