Abstract：An aerodynamic noise analysis model of the simplified inter-coach between the two carriages of a high-speed train is established based on FLUENT software and Virtual-lab software. Using this model analyzes the effects of the Inter-Coach structural style and windshield on aerodynamic noise generation at the inter-coach. Exterior noise distribution and noise radiated sound filed near the inter-coach are shown in the paper. The numerical results show that aerodynamic noise level can be decreased by rounding the edges of the inter-coaching structure and the windshield. In between the carriages of the train, installing the windshield can reduce the aerodynamic noise outside and inside the cavity between the carriages effectively, but the pneumatic noise level at the windshield opening increases. Finally, the windshield is optimized. The optimized windshield has good noise reduction effect.
