Abstract

The layout optimization design for the vertical tail with improved variable density method by introducing the constraint factor is studied in this paper. It finishes topology optimization design of the simplified 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.
