206 密度法による 3 次元構造物の位相最適化

抄録

In this paper, an effective method for the topology optimization of 3D structures is presented. In this method, the structures are analyzed using the finite element method with PCG solver. The density approach is adopted as the topology optimization method. The optimality criteria method is used for solving the optimization problem, and the filtering method is used for preventing the checkerboards in the solution. The effectiveness of the present method is demonstrated by some numerical examples.
