A modified hybrid finite element and boundary element method for rail transit bridge-borne noise analysis

摘要：

　　A modified hybrid finite element(FE)and boundary element(BE)method for analysing the bridge-borne noise is present in this paper.A bridge FE model is established using solid elements in ANSYS at first to calculate the vibration responses of the bridge.Then the bridge vibration responses are applied to the bridge BE model established in SYSNOISE to compute the structure-borne noise.Finally,the modified method is validated by the measured noise results of a 3×40 m continuous rigid frame box-girder bridge on the Guangzhou rail transit line.
