| Abstract: | The coupled fluid-structural acoustic analysis theory,method and processing flow for acoustic cavity modeling was introduced.The noise analysis in ship cabin is carried out.The structure vibration response noise and air noise are considered,which are induced by propeller excitation and air conditioner respectively.And the composite absorber material around the cabin wall and top is considered,too. |
