DEVELOPMENT AND PROSPECT FOR LOW NOISE PANTOGRAPHS

Shinkansen trains run mainly on elevated railways and the noise caused by their running consists of trolley-pantograph noise, body aerodynamic noise, wheel/rail noise, and structure-borne noise. Among these, wheel/rail noise has the biggest energy, but it has been cut off effectively by soundproof walls all along the line. Therefore, for the Shinkansen, reduction of trolley-pantograph noise has been the main problem for the speed-up. The aerodynamic noise has been restrained by installing pantograph covers on the train roof until now. However, since pantograph covers themselves generate aerodynamic noise, a new "low-noise pantograph" without pantograph covers has been developed. This paper introduces the development of the low noise pantograph and insulator, focusing on results of wind tunnel tests. For the covering abstract see ITRD E107776.
