| Abstract:Taking the design and application of small civil ship’s acoustic inlosure of as the research object, with the use of CAD and CAE software, the diesel generator set acoustic inclosure which meets the demand of small civil ship’s vibration and noise reduction was developed through reasonable confirmation of specific indexes and design techniques. Actual application show that the inclosure could reduce vibration by 53 dB，and noise by 26 dB(A), thus meet the design requirements. The design techniques provide technical basis for the follow up design of small low-noise and luxury civil ships. |
