| Abstract:Dong Fang Hong 3 vessel was taken as the research object. At the stage of concept design, according to the preliminary design of the vessel and the type selection of the power system and propulsion system, the method combining empirical formula, engineer experience and numerical simulation was used to carry out preliminary evaluation of underwater radiated noise. Vibration and noise quotas for key power system were assigned. The vibration limitation of hull transmitted from power system, as well as the maximum noise level of the propeller were defined. Thus the vessel can meet with the DNV Silent-R under-water radiated noise srandard at the stage of design, and provides technical reference for follow-up building of high quality research vessels. |
