摘　　要：以某机床厂生产的车铣复合加工中心CX110100为研究对象,通过Solidworks建立加工中心三维实体模型,并对加工中心模型进行了简化。利用ANSYS Workbench有限元分析软件识别结合面特性,建立加工中心的有限元模型。对加工中心有限元模型进行模态分析和谐响应分析,得到加工中心的前6阶固有频率、振型特征和谐响应特性。对得到的固有频率和振型进行分析,指出了引起加工中心振动的薄弱环节,为进一步的设计指明方向。The CX110100 machining center was taken as the research object,which was turned out by a machine tool factory.The three dimensional solid model of the machining center was built by Solidworks and the model was simplified.Characteristic of binding faces was recognized and a FEM model of the machining center was established by ANSYS Workbench.Through modal analysis and harmonic response analysis,the first six orders natural frequencies and vibration characteristics of the machining center were obtained.Through analyzing the natural frequencies and vibration modes,the weak link causing vibration of the machining center was pointed out.It provides guidance for the further optimal design of the machining center.
