style="text-indent:25px">汽車排氣管里的消聲器的原理：就是通過降低、衰減排氣壓力的脈動來消除噪聲。根據(jù)干涉原理，排氣消聲器有吸收、反射兩種基本的消聲方式。吸收式消聲器，通過廢氣在玻璃纖維、鋼纖維和石棉等吸音材料上的摩擦而減小其能量；反射式消聲器則有多個串聯(lián)的諧調(diào)腔與不同長度的多孔反射管相互連接在一起，廢氣在其中經(jīng)過多次的反射、碰撞、膨脹、冷卻而降低其壓力，減輕振動及能量。實際情況下，汽車上多是綜合利用不同的消聲原理組合來設(shè)計排氣消聲器，同時在舒適型要求較高的小型乘用車上還會采用多個消聲器單元進行多級的消聲降噪控制。微穿孔板式消聲器可以控制消聲器的頻譜性能。儋州消聲器批發(fā)報價</p><p

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”。消聲器質(zhì)量</p><p
