摘　　要：本文以起吊设备内门架为研究对象,利用Solidworks软件建立其三维实体模型,并将模型导入ANSYS Workbench中进行有限元分析,得到内门架在最危险工况下的等效位移云图和等效应力云图,由图分析可得其强度和刚度均满足设计要求。然后以其立柱截面尺寸为设计变量,强度、刚度为约束条件,质量最小为目标对内门架进行多目标优化设计,结果显示优化后的内门架在质量减少12%的同时,静态性能也得到改善。The inner mast of Lifting equipment is selected as research contents, the Solidworks soft- ware is used as the 3D solid model establishment, then the model of inner mast is imported into AN- SYS Workbench to finite element analysis and to get the equivalent deformation and stress contours clouds which the inner mast under the most dangerous condition, it＇ s intensity and stiffness meet to the requirement of design. Then regard section size of column as design variables, its intensity and stiffness are constraints, the minimum mass is goal, multi -objective optimization design is carried out on the inner mast. The results show that not only the inner mast after optimization in quality is re- duced by 12%, but also the static characteristics are improved, which provides reference for the im- provement of the inner mast.
