style="text-indent:25px">直管消聲器消聲量的計算:直管式消聲器消聲量主要與通道形式、長度和吸聲材料的性能有關(guān)。消聲量的計算公式為：其中，Φ是消聲系數(shù)，即每米消聲量(dB/m)；P是消聲器通道截面周長(m)；S是消聲器通道截面積(m2)。消聲管道內(nèi)吸聲系數(shù)越大，消聲系數(shù)Φ越大，消聲量越高。增加長度，或增加通道周長與截面積的比P/S，消聲量越大。同樣周長，圓形截面的周長與截面積的比，要比扁狀的矩形小很多，因此，圓形截面的直管式消聲器消聲性能小。當(dāng)直管消聲器截面較大時，如徑尺寸大于30cm的圓管或矩形管，高頻聲波成上束狀，將直接穿過管道，而與管壁的吸聲材料不發(fā)生作用，消聲性能變差，這種高頻性能下降的現(xiàn)象被稱為“高頻失效”。并將高頻消聲量明顯下降的頻率稱為“上限失效頻率”。汕尾消聲器服務(wù)哪家好消聲器主要由消聲筒、消聲片、上下封板（或封頭）、支座、起吊環(huán)、銘牌等零部件組成。</p><div

style="text-indent:25px">抗性式消聲器是由突變界面的管和室組合而成的，好像是一個聲學(xué)濾波器，與電學(xué)濾波器相似，每一個帶管的小室是濾波器的一個網(wǎng)孔，管中的空氣質(zhì)量相當(dāng)于電學(xué)上的電感和電阻，稱為聲質(zhì)量和聲阻。小室中的空氣體積相當(dāng)于電學(xué)上的電容，稱為聲順。與電學(xué)濾波器類似，每一個帶管的小室都有自己的固有頻率。當(dāng)包含有各種頻率成分的聲波進入個短管時，只有在個網(wǎng)孔固有頻率附近的某些頻率的聲波才能通過網(wǎng)孔到達第二個短管口，而另外一些頻率的聲波則不可能通過網(wǎng)孔．只能在小室中來回反射，因此，我們稱這種對聲波有濾波功能的結(jié)構(gòu)為聲學(xué)濾波器。選取適當(dāng)?shù)墓芎褪疫M行組合．就可以濾掉某些頻率成分的噪聲，從而達到消聲的目的。抗性消聲器適用于消除中、低頻噪聲。可使用小孔噴注型消聲器，前提是排放量必需足夠大，不能產(chǎn)生悶壓及節(jié)流，一般為全不銹鋼制造。</p><div

style="text-indent:25px">摩托車消聲器是摩托車發(fā)展史上不可或缺的零部件，摩托車消聲器發(fā)展歷史也與摩托車一樣久遠(yuǎn)。發(fā)動機在做功后，緊接著是排氣沖程。排氣是將氣缸內(nèi)的廢氣排出。由于這時的廢氣是高溫高壓，由排氣管直接排出，將是很大的噪音。而消音器的作用簡單的說，就是發(fā)動機排出的氣流在消音器內(nèi)經(jīng)過多孔的管子與隔板并反復(fù)的回繞后，噪音逐漸衰減，達到消音的目的。消聲器是一個多級分流分壓的組合體。其工作原理大致如下：進氣：此時進氣門打開，活塞下行，汽油和空氣的混合氣被吸進汽缸內(nèi) .壓縮：此時進氣門和排氣門同時關(guān)閉，活塞上行，混合氣被壓縮。燃燒：當(dāng)混合氣被壓縮到較小時火花塞跳火點燃混合氣，燃燒產(chǎn)生的壓力推動活塞下行并帶動曲軸旋轉(zhuǎn)。排氣：當(dāng)活塞下行到較低點時排氣門打開，廢氣排出，活塞繼續(xù)上行把多余的廢氣排出。阻性式消聲器：主要是利用多孔吸聲材料來降低噪聲的。汕尾消聲器服務(wù)哪家好</p><p style="text-indent:25px">有源式消聲器基是使其在一定范圍內(nèi)與原來的聲場相抵消。汕尾消聲器服務(wù)哪家好</p><p style="text-indent:25px">抗性消聲器可以分為5種基本形式：擴張室消聲器、共鳴型消聲器、干涉型消聲器、損耗型消聲器和文氏型消聲器。消聲原理：擴張室消聲器一是利用管道的裁面突變，即聲阻抗的變化使沿管道傳播的聲波向聲源方向反射回去；二是利用擴張室和內(nèi)插管的長度，使向前傳播的波和管子不同界面反射的聲波差一個180度的相位、從而使二者振幅相等、相位相反，互相干涉，達到較理想的消聲效果。共鳴型消聲器常用于消除管道傳播的低頻(350Hz以下)噪聲。干涉型消聲器的消聲原理足將聲波分成兩路，在管道上裝設(shè)一排通管，使管道長度為通管長度的2倍。管道長度等于要消除的聲波的波長，那么通管的長度則為二分之一波長。這樣聲波當(dāng)通過兩種不同長度的途徑時，在管道與通管匯合處將產(chǎn)生振幅相等，位移相反的2種聲波，彼此互相干涉，從而降低噪聲。汕尾消聲器服務(wù)哪家好</p><p
