位相最適化を用いたタービン発電機フレームの構造検討

Until now, we have considered structure of large generators by parametric optimization for weight saving and stiffness improvement. But the improvement effect was often small because substantial structural modification is generally difficult by parametric optimization. So we're studying the most suitable reinforcement structure of generators using topology optimization which is non-parametric optimization. We analyzed by three patterns of geometric constraints and found the most suitable reinforcement structure in the respective conditions. We proved efficacy of topology optimization in frame design of large generators.
