| 摘 要： | 基于ANSYS软件建立了数控铣床工作台的三维有限元模型,对工作台进行了无预紧力和有预紧力情况下的模态分析,分别得出了工作台前4阶的固有频率和振型。分析结果为评定数控铣床工作台的动态特性提供了依据,也为对铣床进行进一步动力学分析打下了理论基础。

| Abstract: | The paper establishes the 3D model of a NC milling machine table,which is based on ANSYS software.The modal analysis of the milling machine table under the condition of having or not having preload is carried out,and the first four natural frequencies and vibration modes of the table are obtained.The results can provide the basis for evaluating the dynamic characteristics of the milling machine and lay a solid foundation for the dynamic analysis of the milling machine. |
