摘　　要：模态分析对于刀具、机床的整体分析非常重要,而结合部又在其中扮演关键角色。就结合部的处理采用等效材料模型的方法来分析整个立铣刀具的模态,创新应用ANSYS的优化模块反求等效材料特性参数。通过对含单层结合部的参数识别进而分析整体含多层结合部的模态,并利用各阶固有频率来验证方法的有效性。The modal analysis is quite important to the whole analysis of machine tools or cutting tools. And the key points lie on how to dealing with the joint interface. In order to analyze the whole model of cutting tools, it proposes the method of using equivalent models with virtual materials provided, describes a new way of deciding the parameters of the virtual materials with the help of the optimization parts in Ansys, provides the parameters of the multi - interface within the whole model by calculating each of the separate joint interfaces. The validity of the method is proved by the measured natural frequency.
