基于Ansys workbench的联轴器膜片响应曲面优化

Response Surface Optimization of Coupling Diaphragm Based on Ansys workbench

利用Ansys workbench平台建立数学模型,对联轴器膜片进行网格划分,并分析其最大等效应力和最大总变形的分布位置及大小,再根据其结构设置结构尺寸的变化范围,计算出有效区间的设计点,最终获得最优设计点,完成膜片的响应曲面优化。结果表明,最大等效应力减小20.3%,最大总变形减小24.7%。可见响应曲面优化后,可以提高膜片联轴器的结构强度,减小膜片联轴器工作中疲劳失效的几率。

Firstly, the paper established a mathematical model of diaphragm, meshed the model, analyzed its maximum equivalent stress and maximum total deformation distribution location and size. Next, it set the variation range of the diaphragm structure according to the its structure, calculated the design points in the effective range. Finally, it obtained the most optimal points. The results show that the maximum equivalent stress is reduced by 20. 3%, the maximum total deformation is reduced by 24. ？%. This shows that response surface optimization can increase the structural strength of the diaphragm coupling, reduce the fatigue failure probability of the diaphragm coupling.
