Vibration and Bridge-Borne Noise from Urban Rail Transit Trough Beam

Abstract:

Article Preview

Vehicle-track-bridge dynamic interaction analysis is applied to compute local dynamic responses of a trough beam under urban rail transit train by mode superposition method. The modal acoustic transfer vectors (MATVs) are obtained by boundary element method. The bridge-borne noise at different field points is then computed based on the MATVs and Fourier spectra of the mode coordinate responses of the bridge. The numerical results show that the noise level is significantly affected by the train speed but hardly influenced by the fastening stiffness. The residents in the high-rise buildings near the bridge may be much affected by the bridge-borne noise.
