基于正交试验设计方法,针对结构拓扑优化中体积系数、惩罚因子和控制半径等参数的组合问题,设计了9种不同的试验组合方案,利用MATLAB软件对这9种方案进行了仿真试验分析,采用极差分析法和方差分析法对仿真结果进行了分析,优选出了结构的刚度达到最大、目标函数的迭代步数最少的参数组合方案,该方案在结构拓扑优化设计中具有较强的泛用性。 Based on the orthogonal test design method, nine different test combination schemes are designed for the combination of volumetric coefficient, penalty factor and control radius parameters in structural topology optimization. The simulation analysis of these nine schemes is carried out by MATLAB software, The results of analysis are analyzed by using range analysis and analysis of variance. The parameter combination scheme with the highest stiffness and the smallest number of iteration steps of the objective function is selected. This scheme has a strong generalized topology in structural topology optimization Usability.
