A Low Vibration Design and Test of Exhaust Pipe System of Vessel Generator Set
In order to reduce the vibration and noise transmission of the exhaust pipe system to the hull structure and the nearby cabin,it is necessary to carry out low vibration design.On the basis of considering the vibration reduction,the natural vi-bration frequency of the exhaust pipe system was considered to select the appropriate vibration reduction components.The modal of the exhaust pipe system was calculated by finite element method,and the vibration isolation effect was tested and verified on the real ship.The results showed that in the frequency range of 10 Hz～10 kHz,the vibration reduction device of the exhaust pipe system has a good vibration isolation effect,and the vibration isolation effect reaches more than 15 dB.The equipment dam-age,serious vibration and noise caused by the resonance of the whole system were effectively avoided.
