Abstract

Under the dynamic load of vehicle, the box beam will vibrate and radiate low- frequency noise which is harmful to human health. By taking a 32m rail transit box beam as example, the finite element method is adopted to establish the model of the box beam, which one with web plate hole and another no holes. After calculating the vibration response of box beam under the action of a train, analysis the structure noise radiation characteristics of box beam with web hole by adopting the finite element coupled acoustic boundary element method. The results show that web opening can reduce the vertical vibration of box beam roof and floor; Box beam web hole change the direction of box beam structure noise attenuation and has a good noise reduction effect below box beam and far sites. The analysis results can provide some theoretical reference for the design of reducing vibration and noise of urban rail transit box beam.
