| Abstract: | Statistical energy analysis (SEA) is adopted to predict the ship noise at medium and high frequency bands. A submarine model is set up by using AutoSEA. SEA theoretical analysis shows that the air noise in the engine room and radiation noise are reduced by adding thickness of the left and right ground floors and decreasing the isolator the rigidity springs, which is agreed with AutoSEA simulation results. It is demonstrated that statistical energy analysis and AutoSEA could be used in the ship noise prediction. |
