汽車消聲器的作用:
1、主要是用于減少降低汽車發動機工作時產生的噪聲;
2、消聲器的原理是汽車排氣管由兩條不同長度的管子組成,兩條管子分開后相交,因為兩條管子之間的長度差等于汽車發出的聲波波長的一半;
3、使兩列聲波在相互干擾的疊加中相互抵消,降低聲強,使發射的聲音減小,從而起到消聲器的作用。
消聲器的作用是指在氣流管道中同時傳播噪聲,可與管道和彎管的吸聲襯里或利用截面積的突變等聲阻抗間斷管道等消聲裝置,使管道中的噪聲減弱得到衰減或反射回來。
汽車消聲器的作用,顧名思義肯定就是消除汽車上的噪音。
汽(qi)車(che)排氣管消聲器的位置(zhi):
1、汽車消(xiao)聲(sheng)器(qi)按消(xiao)聲(sheng)原理與(yu)結構(gou)可(ke)分為抗性消(xiao)聲(sheng)器(qi)、阻(zu)性消(xiao)聲(sheng)器(qi)和阻(zu)抗復合型消(xiao)聲(sheng)器(qi)三類(lei);
2、抗(kang)(kang)性(xing)(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi): 抗(kang)(kang)性(xing)(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)是在(zai)內部(bu)通(tong)過管道、隔板(ban)等部(bu)件組成擴張(zhang)室、共振室等各種消(xiao)聲(sheng)(sheng)(sheng)(sheng)單元時(shi),聲(sheng)(sheng)(sheng)(sheng)波(bo)在(zai)傳播時(shi)發生反射和干涉,降低聲(sheng)(sheng)(sheng)(sheng)能量達(da)到消(xiao)聲(sheng)(sheng)(sheng)(sheng)目的。抗(kang)(kang)性(xing)(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi)消(xiao)聲(sheng)(sheng)(sheng)(sheng)頻帶有限,通(tong)常對低、中頻帶消(xiao)聲(sheng)(sheng)(sheng)(sheng)效果好,高(gao)頻消(xiao)聲(sheng)(sheng)(sheng)(sheng)效果差,貨車(che)多采用抗(kang)(kang)性(xing)(xing)消(xiao)聲(sheng)(sheng)(sheng)(sheng)器(qi)(qi);
3、阻性消(xiao)(xiao)聲(sheng)(sheng)器(qi) :在內部(bu)排(pai)氣(qi)通過的管(guan)道(dao)周圍填充吸聲(sheng)(sheng)材料(liao)來(lai)吸收聲(sheng)(sheng)能(neng)量達到消(xiao)(xiao)聲(sheng)(sheng)目(mu)的的消(xiao)(xiao)聲(sheng)(sheng)器(qi)。對中、高(gao)頻消(xiao)(xiao)聲(sheng)(sheng)效(xiao)果好,單純用作汽車排(pai)氣(qi)消(xiao)(xiao)聲(sheng)(sheng)器(qi)較少,通常與抗性消(xiao)(xiao)聲(sheng)(sheng)器(qi)組合起來(lai)使用;
4、阻(zu)抗復合(he)型消(xiao)(xiao)聲(sheng)(sheng)(sheng)器: 分別用抗性(xing)消(xiao)(xiao)聲(sheng)(sheng)(sheng)單元(yuan)和吸聲(sheng)(sheng)(sheng)材(cai)料組合(he)構(gou)成的消(xiao)(xiao)聲(sheng)(sheng)(sheng)器,它(ta)具有(you)(you)抗性(xing)、阻(zu)性(xing)消(xiao)(xiao)聲(sheng)(sheng)(sheng)器的共同(tong)特點。對低、中、高頻噪聲(sheng)(sheng)(sheng)都有(you)(you)很好的消(xiao)(xiao)聲(sheng)(sheng)(sheng)效果。
