Review of the mitigations the exterior noise level of EMU
- 발행 : 2014.04.23
초록
To reduce the exterior noise level of EMU, there are several ways have been evaluated. The noise sources for the exterior noise level are the traction motor, driving gear and wheel/rail rolling noise. In this article, the ways to mitigate the noise issue for EMU have been investigated and especially the way to protect the noise radiation from the bogie area and wheel/rail rolling noise. The way to evaluate the effect of the side skirt has been reviewed. To install the side skirt, the interface between the side skirt and the carbody and bogie should be examined and the acoustic design of the side skirt will be evaluated.
