多分割舟体試作機の接触性能評価

In developing a pantograph of a high speed train, reducing aerodynamic noise of the pantograph is one of the most important subjects. For reducing this noise, suitable configuration of pantograph head, which has a smooth cross section profile, is investigated. However, the pantograph head with smooth cross section profile and conventional support system of contact strip sometimes wreak undesirable lift force characteristic. Authors are developing multi-segment pantograph head, which has a new support system without deterioration of lift force characteristic. This paper describes the validation result of this support system by model analysis and some test bench.
