A Study on the Prediction of the Noise Reduction Performance According to Applying the Rail Web-Damper in Curved Track Section

초록

This research plans to consider noise reduction performance of the rail web-damper in curved track section. For this purpose, we predicted vibration and noise and analyzed noise reducing elements. Firstly, the predictive value of vibration and noise was calculated by the BEM based program and numerical analysis toward the curved track section in the tunnel. Also, the actual noise value was compared with the predictive noise value from track component vibration, such as sleeper and the rail before & after applying rail web-damper
