    MTMDs-Based Noise Control for Box-Girder Bridge of High Speed Railway

    MTMDs-Based Noise Control for Box-Girder Bridge of High Speed Railway


    Abstract The environmental issues induced by the high speed railway become more and more serious with its rapid development. In order to control the low-frequency structure noise of the box-girder bridge of high speed railway, this paper proposes a new idea that the multi-mass-dampers (MTMDs) may be used. A sound radiation analysis model of the box-girder bridge is developed to validate the idea and to evaluate the control effect. Firstly, a vehicle-track-bridge coupled dynamic model is established to obtain the dynamic responses of the box-girder bridge induced by the excitation of German railway spectra of low irregularity. Then the sound radiation analysis model of the box-girder bridge is established using boundary element method and the dynamic responses are used as the boundary condition to solve the acoustic radiation characteristics of the box-girder bridge. The mechanism of noise radiation of the box-girder bridge is analyzed combined the acoustic radiation efficiency, the vibration response and the vibration distribution. Finally, the MTMDs are using to control the noise radiated by the box-girder bridge based on its mechanism of noise radiation and the control effect is evaluated.
