When increasing the speed of Shinkansen trains, it becomes more important to reduce noise generated from cars. In the past, East Japan Railway Company developed a low-noise pantograph (PS208 type) to equip on the Series E5 Shinkansen trains that was able to reduce aerodynamic noise emitted around pantographs. However, with plans for greater increases in speed, pantograph-based noise continues to be an issue, as it has been one of the major noise sources even on the Series E5. In this study, we first investigated the noise source of the existing PS208 and found that noise is mostly generated from the four following areas: base of the lower arm, hinge cover between the upper and lower arms, pantograph head, and pantograph head support. Next, as countermeasures for these noise sources, we conducted wind tunnel tests and numerical simulations to test for improved shapes. As a result, we developed a new pantograph (PS9040), with 1.5 dB less aerodynamic noise than the PS208.
