| Abstract:Radiated noise simulation of the middle speed diesel for a passenger liner is studied, and the calculation modeling, loading and acoustic pressure computing method of the marine diesel are also dis- cussed. The influence of engine＇ s main components on the whole engine＇s vibration noise is studied, and the acoustic evaluation of the diesel engine＇s radiated noise is accomplished, which could be applied in the noise reduction design of the passenger liner＇ s main propelling diesel. |
| Key words: marine diesel noise simulation |
