Study on the reduction of noise and vibration caused by the cooling fan in EMU at stationary

구동전동기의 강제 냉각용 Fan이 적용된 전동차의 소음 진동 저감방안 적용연구

In general, the rolling stock has been designed and manufactured in accordance with the requirements of purchaser. The requirements of the noise and vibration performance are called the international standard (ISO, UIC, TSI etc.) and are demanded based on the special conditions for the regional regulation and the characteristics for operating condition in detail. In this paper, the noise and vibration performance in the train at stationary condition has been investigated and the design parameter of the cooling fan to control the noise and vibration performance has been examined.
