The vertical tail of topology optimization design study based on improved variable density method

研究引入约束因子的改进变密度法的飞机垂尾布局优化设计问题。用MATLAB编写的带约束因子变密度法的算法程序和ANSYS软件的拓扑优化模块,分别完成简化模型的拓扑优化设计,实现飞机垂尾的结构布局设计。给出了两种方法的优化结果和优化数据,对比分析可以发现带约束因子变密度优化方法是可行和有效的,相较ANSYS软件的拓扑优化模块针对飞机垂尾的结构布局设计更加简便、准确,有着更好的推广应用价值。

The layout optimization design for the vertical tail with improved variable density method by in- troducing the constraint factor is studied in this paper. It finishes topology optimization design of the simpli- fied model of the vertical tail using MATLAB program for variable density method with constraint factors and ANSYS topology optimization module. The paper presents the optimization results and optimization data of the two methods, finds that the variable density method with the constraint factor is feasible and effective with comparison and analysis. The structure layout design of the vertical tail is simpler and more accurate, and has a better application value than ANSYS.
