摘要：
The vibration energy generated by the internal equipment of the underwater vehicle is coupled and transmitted by side panel and internal medium of the water cabin, and generates radiation noise in the external field, which becomes a weakness of ship mechanical noise control. In this paper, an analytical coupled model of sound and structre vibration is established for the challenge of water cabin external acoustic radiation control. Both the internal and external sound field influence is considered. The vibration and acoustic power transmitted by side panel and internal medium is calculated, the influence of both transmitt paths is given. An effective reduction of external acoustic radiation can be achieved by lining acoustic coating and reducing the stiffness of side panel, providing a new idea for the control of acoustic power transmitting through water cabin. © 2019, Editorial Board of Journal of Ship Mechanics.
