济南装载机http://m.132p.cn/产生的排气噪声主要是排气系统辐射出来的总噪声，包括管壁的辐射噪声、消音器壁的辐射噪声和尾管出口的启动辐射噪声。
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.
   
济南装载机产生排气噪声的主要原因是在装载机柴油机工作过程中，在排气阀的地方，气体流动不稳定，气流以压力波动的方式传到了排气系统的出口，在尾管出口处，连速度波动产生了不规则噪声，以简单的理解是排气系统内气流不稳定引发了排气噪声。
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.
   
若将排气系统的管壁和消音器壁假设为刚性的，则排气噪声指的是仅气体动力性噪声，降低济南装载机http://m.132p.cn/排气噪声最有效方法就是设计安装一个高效、低阻力的排气消音器。
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.
