In order to reduce the influence of vibration and noise produced by air conditioning system of an underground plant on the precision instrument test platform,a comprehensive treatment for vibration and noise reduction of air conditioning system is presented,applying specializedair bag isolation,flexible arc pipe,elastic clampand other vibration isolation components to achieve a vibration isolation of 45dB for the air conditioning unit,applying array muffler,double-layer micro perforated sound-absorbing panels,and other noise reducing components to reduce the air noise of the testing workshop by 22dB(A).After the comprehensive treatment,the linear acceleration of the test platform foundation is decreased by 13.55dB,which can meet the micro vibration environment requirements of the plant test platform.
