Abstract
The numerical prediction of the low-frequency self-noise of the sonar platform with sound absorbing wedge is carried out. Considering the acoustic-solid coupling effects of sonar district in the flow field, the structural response of the platform and sound radiation pressure is calculated. The vibration characteristics of the sonar platform and the vibration/noise reduction of the sound absorbing wedge are analyzed. Based on the sound absorbing wedge laying methods, four arithmetic conditions are designed. The influences of different covering arrangement on the acoustic radiation characteristics of the sonar platform are compared.
