A Structural Topology Optimization Method based on SIMP and Conductive Weight Method
摘要
With the research and development of topology optimization methods, in order to improve the engineering manufacturability of optimized structures, some scholars have proposed different methods. In this paper, the optimization criterion method is replaced on the basis of SIMP, and the guide weight method is used, and the optimization criterion method is compared. Firstly, the Lagrange function is performed on the continuous topology optimization model to solve the problem of least flexibility. Then, the density update is performed on the Guide-weight method and the optimization criterion method. Finally, the Hesviside function is used for filtering to avoid the generation of grayscale elements. After a two-dimensional study and a three-dimensional study, it is concluded that the engineering manufacturability of the optimized structure obtained by the guide method is better than that obtained by the optimization criterion method.
