Abstract

Here, to study characteristics of noise inside metro train in tunnel, the tunnel-car body finite element-acoustic boundary element analysis model was established. Based on the Metro B type car-rail coupled model and field tests, the car body secondary suspension force excitation and wheel-rail noise excitation were obtained. These excitations were exerted on the car body to simulate and analyze noise inside metro train. The simulation results were verified with the train noise test data of Guangzhou rail transit line 7, and effects of structural borne noise and airborne noise on noise inside metro train were studied. The analysis results showed that the change trend of sound pressure level diagram of each standard point in train is basically the same, the peak center frequency is concentrated at 630 Hz, the main frequency band is 200-1 600 Hz, the A sound level at the upper of car body bogie is about 1.02-2.35 dB (A) higher than that at car body center; the main influence frequency band of structure borne noise on car interior noise is 20-200 Hz, the main influence frequency band of airborne noise on car interior noise is 200-5 000 Hz, effects of the frequency band of 500-5 000 Hz are the most significant; when the train running speed is 60 km/h, the A sound level at car center under action of structural borne noise load is about 21 dB (A) higher than that at car center under action of airborne noise load; the study results can provide a theoretical basis for reducing car interior noise and improving car interior acoustic environment.
