濟(jì)南裝載機(jī)http://m.hdwzhs.com/產(chǎn)生的排氣噪聲主要是排氣系統(tǒng)輻射出來的總噪聲，包括管壁的輻射噪聲、消音器壁的輻射噪聲和尾管出口的啟動(dòng)輻射噪聲。
Jinan loader exhaust noise generated by the exhaust system is mainly out of the total noise radiation, including radiation noise wall, radiated noise muffler and tail pipe wall outlet start radiated noise.
   
濟(jì)南裝載機(jī)產(chǎn)生排氣噪聲的主要原因是在裝載機(jī)柴油機(jī)工作過程中，在排氣閥的地方，氣體流動(dòng)不穩(wěn)定，氣流以壓力波動(dòng)的方式傳到了排氣系統(tǒng)的出口，在尾管出口處，連速度波動(dòng)產(chǎn)生了不規(guī)則噪聲，以簡(jiǎn)單的理解是排氣系統(tǒng)內(nèi)氣流不穩(wěn)定引發(fā)了排氣噪聲。
The main reason Jinan Loader exhaust noise is generated in the course of the loader diesel engine, the exhaust valve in place, the gas flow is unstable, the air pressure fluctuation mode exhaust system reached the exit, at the outlet of the tail pipe even speed fluctuations irregular noise, a simple understanding is the exhaust system airflow exhaust noise caused instability.
   
若將排氣系統(tǒng)的管壁和消音器壁假設(shè)為剛性的，則排氣噪聲指的是僅氣體動(dòng)力性噪聲，降低濟(jì)南裝載機(jī)http://m.hdwzhs.com/排氣噪聲最有效方法就是設(shè)計(jì)安裝一個(gè)高效、低阻力的排氣消音器。
If the wall of the exhaust system and muffler wall is assumed to be rigid, the exhaust noise refers only aerodynamic noise, Jinan loaders most effective way to reduce exhaust noise is the design and installation of a high efficiency, low resistance row gas muffler.
