摘　　要：数控回转工作台是大型数控镗铣床等机床的直接承载附件,其结构特性对整机性能有很大影响。针对HTK200B回台的工作台部件,进行了有限元分析,得到了工作台的前五阶模态频率与静力学变形;对工作台进行模态试验,验证了工作台模态仿真分析模型的正确性,为下一步进行结构优化提供了理论指导。CNC rotary table is the direct bearing member of CNC milling and boring machine tools, whose structural characteristics have a huge influence on CNC rotary table. For the table component of HTK200 B CNC rotary table, finite element method was used to obtain table＇s deformation at the maximum load in this paper. The top five modal frequencies were got too. In order to verify the correctness of modal simulation, modal test was done, which also provided a theoretical guide for next structural optimization.
