柴油發電機組噪聲源分析 
柴油(you)(you)發動(dong)機(ji)(ji)(ji)(ji)組噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)是由多種聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)源構成(cheng)的復雜聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)源。按(an)照(zhao)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)輻射方式, 它可分(fen)為空(kong)氣動(dong)力(li)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)、表面輻射噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)和(he)電磁噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)。按(an)照(zhao)產生的原因(yin), 柴油(you)(you)發電機(ji)(ji)(ji)(ji)組表面輻射噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)又可分(fen)為燃燒噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)和(he)機(ji)(ji)(ji)(ji)械噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)。其(qi)中空(kong)氣動(dong)力(li)噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)為柴油(you)(you)發動(dong)機(ji)(ji)(ji)(ji)組噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)的主要噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)源。柴油(you)(you)發電機(ji)(ji)(ji)(ji)組噪(zao)(zao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)的控制措施，排風(feng)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)，柴油(you)(you)發電機(ji)(ji)(ji)(ji)組依靠自(zi)帶(dai)風(feng)扇排風(feng)，在(zai)排風(feng)房(fang)前部安裝(zhuang)(zhuang)AES型矩形消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)，消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)尺寸(cun)為1.2m×1.1m×0.9m，消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)內(nei)裝(zhuang)(zhuang)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)片厚200mm,間(jian)距100mm。消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)片采用兩側鍍(du)鋅穿孔板夾超細玻璃棉結構。9個相同尺寸(cun)的消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)拼裝(zhuang)(zhuang)成(cheng)1個1.2m×3.3m×2.7m的大型消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)。消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器(qi)前300mm處為相同尺寸(cun)的排風(feng)百葉窗。
