進化アルゴリズムによるパンタグラフ舟体三次元形状の空力特性最適化システムの開発

抄録

In high-speed pantograph, it is important that achieving stable current collections and reducing aerodynamic noise. These characteristics are influenced by the pantograph head shape. We developed a multi-objective optimization system using LES and an evolutionary algorithm and conducted the optimization of a three-dimensional panhead shape considering flow between the pan support and the panhead to adjusting the lift force to the target and reducing aerodynamic noise. In the results of the optimization, we obtained the correlation of control points and objective functions.
