摘　　要：针对T形结构传统设计周期长、材料利用率低、设计成本高等问题,使用SolidWorks建立数字模型,将其转换成ANSYS Workbench可读的格式文件,进行拓扑优化设计。对T形结构在载荷作用下进行最优化设计,建立以单元材料密度为设计变量,以结构最小柔顺度为目标函数,以质量减少百分比为约束函数的数学模型。采用ANSYS Workbench的Topology Optimization模块进行拓扑优化设计,对比优化前、后结构的应力和变形,可知运用拓扑优化技术实现T形结构的轻量化设计合理有效。As to the issues that the design cycle of the traditional design of T-shape structure is long, the material utilization ratio is low and the design cost is high, a digital model is built using SolidWorks, the model is converted to the readable format file of ANSYS Workbench, and the topology optimization design is performed. The optimal design of T-shape structure under load is carried out. A mathematical model is built, in which the unit material density is design variable, the minimum structural compliance is objective function, and the percentage of mass reduction is constraint function. The topology optimization design is carried out using Topology Optimization module of ANSYS Workbench. The stress and deformation of optimized structure is compared with the initial one. The results show that the lightweight design of T-shape structure using topology optimization technology is reasonable and effective.
