【摘要】 针对CMOR重载机械臂第六关节的轻量化要求，基于ANSYS Workbench对该关节壳体进行结构优化设计。首先对壳体进行有限元分析，然后建立以柔度为目标函数的拓扑优化模型，并从优化结果中提取尺寸设计参数，再通过响应面法构建多目标优化模型，完成尺寸优化。结果表明，优化后壳体在变形与应力满足设计要求的同时，减重率达22.75%,且保证了机械臂抗振性能良好。更多还原

【Abstract】 For the sixth joint the CMOR(CFETR multi-purpose overload robot),the shell structure of the joint is optimized based on ANSYS Workbench.Firstly, the finite element analysis of the shell is carried out.Then, the topology optimization model is established with the flexibility of the shell structure as the objective function, and the dimension is extracted as the design parameter from the optimization result.Then the multi-objective optimization model is constructed by the response surface method, and the dimension optimization is completed.The final results show that after the optimization, the weight reduction rate of the shell is 22.75% under the premise of ensuring that the maximum deformation and maximum stress meet the design requirements, which also ensures the vibration resistance of overall CMOR.更多还原
