Abstract

Wind tunnel test of a new pantograph, that is developed through the KHST project, was performed in RTRI wind tunnel test center of Japan end of last June. This paper indtroduces the measurement results and analysis of noise measurement part that is achieved during the wind tunnel test. The maximum measured sound pressure level at 5m shows 102.3dB(A) at 350km/h and it leads to 88.3dB(A) of predicted sound pressure at 25m that satisfy 91dB(A) of evaluation criteria. Major noise sources of the pantograph was identified as a link between upper and lower arm, panhead contact strips and shunt wires.
