Influence of Vehicle Suspension System Parameters on Acoustic Radiation Characteristics of Rubber Floating Plate Structure

Rubber floating slab track (RFST) with good performance is taken as the research object in the paper. The vehicle-RFST coupling dynamic model and the acoustic (BE) model of RFST were established, then the numerical simulation method detailed studied the influence of vehicle suspension system parameters on the acoustic radiation characteristics of RFST structure. The results show that the main vibration frequency band of the RFST is 50–100 hz; the radiated sound field of the RFST is approximately symmetrical; the vertical stiffness of vehicle single stage suspension has a certain influence on the acoustic radiation characteristics of the track with the RFST; when vehicle suspension system parameter is taken into consideration, the theoretical research on vibration and sound characteristics of the vibration track would be more effective; the magnitude of 106 is the best choice for the vertical stiffness of the single stage suspension of vehicles from the perspective of the acoustic radiation characteristics of RFST.
