Research on high efficiency and low noise cooperative control of fan rom for integrated research vessel
In order to reduce the transmission of vibration and noise of engine room fan to hull structure and nearby cabins,it is necessary to control it with high efficiency and low noise.In this paper,combined with the layout of the fan room of a comprehensive research vessel,the synergistic effect of measures such as fan vibration isolation treatment,wall sound absorption and insulation treatment,muffler layout and so on is analyzed,and it is verified by the real ship test.The results of a real ship show that after the coordinated control measures of high efficiency and low noise are adopted in the fan room,the vibration isolation device of the engine room fan has a good vibration isolation effect,and the vibration isolation effect can reach more than 15 dB.The noise sound pressure level at the outlet of the louver in the fan room lm is lower than the limit requirement of 75 dB(A)in the open entertainment area.This study can provide theoretical reference for low noise cooperat-ive control of ship fan room,and has certain engineering guiding significance.
