摘　　要：应用有限元法在两种工况下对铣头进行了模态分析,得到其固有频率、模态振型等参数。分析结果表明,铣头的固有频率与A轴的工作角度无关,铣头壳体是影响铣头整体动态性能的薄弱环节。该分析为企业对铣头及机床的进一步结构设计和优化提供了重要依据。The dynamic analysis of the milling head is carried out using finite element method in two conditions to get the parameters, such as innate frequency, modal vibration and so on. According to the analysis result, the innate frequency of the milling head has nothing to do with the working angle of shaft A. The milling head shell is the weakest link that influences the whole dynamic property of the milling head. The research method and result are important bases for the enterprise for further structural design and optimization of the milling head.
