摘　　要：利用CATIA三维软件对电液伺服试验机立柱进行建模,并进行静动态分析。利用HyperWork/OptiStruict以单元密度为设计变量,以节点合位移最大化和体积分数最小化为目标函数对立柱结构进行多目标拓扑优化。优化结果表明,在相同受力情况下,立柱的第一阶固有频率和最大变形量均在设计允许范围内,立柱质量减轻了6.58%。With 3D CATIA,a model is built for the electro hydraulic servo testing machine column.By both the static and dynamic analysis based on HyperWorks/OptiStruict module,we take the cell density as design variable,and maximum displacement at the nodes and minimum volume fraction as objective functions to make the multi-objective topology optimization.The results show that the first order natural frequency and maximum deformation of the column are within allowable range when the stress distribution is the same.The weight of the column is reduced by 6.58%.
