Keywords: hybrid FE-SEA method, sound transmission loss prediction, body structure of high-speed train.

Summary

The frame of a high-speed car body is made of beams and hollow double-skin aluminium alloy panels with ribs of composite structure which has a very high stiffness and complexity, so that the sound insulation simulation of this structure is a typical mid-frequency problem. In this paper, the hybrid FE-SEA method was used to solve this problem. Two different hybrid FE-SEA models based on reverberation chamber and DAF-SIF theories were built. On comparing the results, the sound transmission loss prediction of the two models predictions were identical, and when the simulation results were compared with test values, it was shown that in the middle frequency range of 100Hz ~ 1000Hz, the hybrid FE-SEA could predict sound transmission losses of the body structure efficiently and rigorously.
