摘　　要：研究了弧面分度凸轮机构的固有频率及其模态分析。通过建立弧面分度轮机构的等效质量体动力学模型,分析其受力情况,推导出6阶模态固有频率方程,并结合实例,系统地介绍了弧面分度凸轮机构的模态分析步骤与过程,为进一步进行弧面分度凸轮机构设计时避免共振的发生奠定了基础。The natural frequency and modal analysis of globoid indexing cam mechanism are studied.Through the establishment of equivalent mass dynamics model of the globoid indexing cam mechanism,the force condition is analyzed and the equation of six order modal natural frequency is deduced. Combining with the example,the modal analysis process and step of the globoid indexing cam mechanism are introduced,and the foundation for avoiding the resonance during the further design of globoid indexing cam mechanism is provided.
