双方向走行を考慮したパンタグラフ舟体・舟支え部の空力音低減

抄録

Reduction in aerodynamic noise emitted from a pantograph is an important subject for reducing environmental impact and speed-up of Shinkansen trains. In this study, reduction of aerodynamic noise emitted by pantograph head and its support considering bidirectional train operation was investigated. As a result, it is clarified that combination of applying smooth profile pantograph head considering bidirectional operation and applying porous material to pantograph head support can reduce aerodynamic noise in both knuckle forward and knuckle backward orientation.
