| Abstract: | Based on the submarine structure, the vibration and acoustic radiation behavior of the submarine is studied with SEA method. In this paper, a fluid-structural coupling model, including shell structure, vibration isolator, engine and water, is created. Acceleration level and radiated acoustic pressure are calculated using different structural parameters of vibration isolator and cylinder shell. The results of vibration transmission and acoustic radiation in broad frequency band for the submarine is obtained by analysis and experiment. The analysis method can be further used for acoustic prediction and design of a real submarine. |
