摘　　要：运用结构动态设计原理和有限元法的变量化分析技术,用ANSYS软件对加工中心立柱部件进行静力分析和模态分析。通过研究立柱内部三种不同结构肋板对其静、动态性能的影响,给出内部肋板的最佳结构形式。The design method and it＇ s process of columns structure of machine center are pnoposed based on dynamic design principle and variation analysis technology by finite element method （FEM）. With ANSYS software, the static analysis and modal analysis to the column of the machining center are done. The, influence by the inner frame in column to the static and modal performance is researched. Through three structures calculated, the best frame of column is found out. The method of the paper is an example for the effective design to the big parts of machine tool.

关 键 词：立柱 有限元分析 静力分析 模态分析
