摘要：
Based on the 1:1 computational model of a single-shell underwater ship, typical mechanical exciting loads were applied and the radiated noise was obtained by using the sono-elastic method in Pekeris hydro-acoustic waveguide. The radiated noise of the model was analyzed both under the water-surface condition in extremely shallow water environment and under the underwater condition in shallow water environment. The characteristics of the radiated noise under the water-surface condition in extremely shallow water environment were analyzed quantitatively. Besides, the difference of the characteristics of the radiated noise under these two conditions was investigated. © 2019, Editorial Office of Journal of Vibration and Shock. All right reserved.
