ANSYS-Based Static Analysis and Multi-Objective Response Surface Optimization Study of Transmission Shafts

基于ANSYS对大型球磨机衬板更换机械手的传动轴进行静力学分析与多目标优化研究。首先在SolidWorks中建立传动轴的三维模型，并将其导入Workbench进行结构静力学分析，发现传动轴所受应力远小于材料的抗扭强度，具备优化空间。在此基础上，以响应面方法为基础，对该传动轴的结构进行了优化设计，并通过仿真验证了模型的正确性。计算结果表明，该方案可使传动轴的重量减轻1.8%，最大变形减小18.5%，最大应力减小12%，对同类传动轴的设计具有一定的借鉴意义。Based on ANSYS, a static analysis and multi-objective optimization of the drive shaft of a large ball mill liner replacement manipulator is carried out. Firstly, the three-dimensional model of the drive shaft is established in SolidWorks and imported into Workbench for structural static analysis, and it is found that the stress on the drive shaft is much smaller than the torsional strength of the material, which has the space for optimization. On this basis, the structure of this drive shaft is optimized and designed based on the response surface method, and the correctness of the model is verified by simulation. The calculation results show that the scheme can reduce the weight of the drive shaft by 1.8%, the maximum deformation by 18.5%, and the maximum stress by 12%, which is of some significance for the design of similar drive shafts.
