It showed that the vibro-acoustic coupling model of the ship cabin in this paper was effective. Then, the numerically computational sound pressure was compared with experimental results, and a good consistency was presented.
Firstly, this paper established the finite element model of a ship cabin, computed structural response, took the structural response as boundary condition and input it into acoustic software to couple with boundary element model, realize the computation of vibro-acoustic coupling and obtain sound pressure response. This paper combined finite element method with boundary element method to study and improve the noise of ship cabins. The convention sets a high limitation for noises of ship cabins. Ship cabins are places for the crew to be on duty and have a rest.
