Rail Vibration and Rolling Noise Reduction Using Tuned Rail Damper for Vulcanized Bonded Baseplate
Work was conducted on a curved track section of 350 m radius on an underground line where excessive in-car noise was experienced by passengers. Vulcanized bonded baseplates were installed on the section. Investigation was performed comprising initial in-car noise and carriage floor vibration level assessments, testing of rail surface roughness, rail vertical and lateral vibration responses during train normal operation, and measurements of track decay rate. A rail web damper designed for in-car noise control was evaluated on a trial section of track. All experimental data were analysed, showing that the highest LAₘₐₓ was about 95 dB and the highest LAeq 91 dB for the Egg Fasteners Section. 1/3 octave band peak frequencies of dominant in-car noise is at 250 Hz and 315 Hz, consistent with those of rail roughness and rail vibration spectrum. Reduction of rail vibration velocity is not obvious in these frequency bands on the track with rail web damper installed.
