摘要
采用消声、隔振、吸声和隔声相结合的综合方法,控制和减小柴油发电机房的噪声,使柴油发电机组静音箱达到降噪静音的目的。通过分析柴油发电机组的各类噪声声源产生原理,提出消减噪声的措施,对现行柴油发电机组静音箱的结构方案进行分析探讨,并以实际案例进行论证。
The comprehensive method of combining noise reduction,vibration isolation,sound absorption and sound insulation is used to control and reduce the noise of the diesel generator room,so that the silent box of the diesel generator set can achieve the purpose of noise reduction and mute.Through the analysis of the principle of various sound sources,the measures to reduce noise are proposed,and the structure scheme of the current silent set of diesel generator sets is analyzed and discussed,and supplemented by the case as evidence.
