动力学分析对于并联机床的设计有着重要的意义,本文应用有限元软件ANSYS,针对一种三自由度并联机床,建立了并联机床驱动分支的有限元模型,并对其进行了模态分析,分别获得了相应的5阶固有频率及其对应的振型图,其结果可以作为并联机床整机模态分析的重要参考。

Dynamic Analysis is very meaningful for parallel machine tools.In this paper,based on the finite element ANSYS software,the finite element model of driving branch for parallel machine tools is built,and the modal analysis is carried out.Five natural frequencies,and their corresponding mode shapes are respectively obtained.By means of the results,they can provide important reference for modal analysis of parallel machine tools.
