摘　　要：利用ANSYS软件建立加工中心工作台的有限元模型,对工作台模态特性进行分析,得到前3阶模态频率和振型;应用PolyMAX方法对工作台进行实验模态分析。通过对比计算模态与实验模态的分析结果,验证有限元模型的合理性,为工作台结构的合理设计与改进提供理论依据。The finite element model of the CNC table was established with ANSYS,and the modal characteristic of the table was simulated.The first three natural frequencies and vibration modes of the table were obtained.The PloyMAX method was applied to analyze the experimental modes of the table.By comparing the results of computational modes and experimental modes,the finite element model was verified rational.It provides a theoretical basis for the rational design and improvement of the structure of the table.
