改良型ESO法を用いた骨組構造の位相最適化

抄録

In this paper, an improved ESO (Evolutionary Structural Optimization) method for topology optimization of frame structures is proposed. In this method, in the optimization process, the elements with low strain energy are deleted based on ESO method until the target total member mass is reached. Next, when the target total member mass is reached, the elements around the element with high strain energy are added. The above two processes are repeated to find the optimal solution. The effectiveness of the proposed method is shown by comparing the solution of this method with the solutions of mathematical programing method.
