Train Internal Noise Due to Wheel-Rail Interaction

CODEN: JTEVAB

Abstract

In order to investigate different potentially effective methods to decrease the noise inside passenger trains, this article employs the acoustic-solid coupling theory and the finite element (FE)-statistical energy analysis (SEA) hybrid method to study the vibration response of the train body under wheel-rail excitation and the internal noise response caused by the vibration of the train body. The contribution of plates to the noise inside the train is also analyzed. The results show that the vibration of the floor has the greatest influence on the noise inside the train. Furthermore, compared with the FE method alone, the FE-SEA hybrid method shortens the computation time and improves the efficiency of the calculation.
