摘要
Abstract
In order to reduce the wheel-rail noise in Beijing Subway Line 10, the wheels with the sound absorber slices in-stalled had been applied. In fact, good effect of noise suppression had been obtained in the actual operation. The train whistle had been effectively suppressed when the train traveled through the curved track. However, fracture of the installation bolts of the sound absorber slices used to occurring in the operation. The broken bolts might be left in the switch areas which would bring about tremendous security risks for the operation. In this article, the actual wheels were re-processed with the sound absorber slic-es replaced by the sound absorber rings. The wheel-rail noise of the re-processed wheels was tested in the operation. The effect of the noise reduction of the wheels was verified, and the security risks due to the broken bolts were eliminated.关键词
