流体圧力変動に対するロバスト性を考慮したトポロジー最適化技術の開発

抄録

As a product moves through the fluid, it may experience fluid pressure variations due to usage condition changes, which may affect the performance of the product. Therefore, when designing the product, it is necessary to consider the robustness. In this research, we have developed a topology optimization technique incorporating fluid pressure variance into the objective function in order to be able to derive a structure that is robust to changes in usage conditions. In the verification model, it was obtained a robust optimum design that realizes smaller variance in maximum displacement against fluid pressure variations due to usage condition changes.
