气制动柴油机泵气系统噪声研究

Research on Noise of Pump Gas System of Air Brake Diesel Engine

我们分析了排气卸荷型气制动柴油机泵气系统工作原理及噪声机理,通过对打气泵、干燥器、储气筒工作噪声进行专项调查,找出泵气系统主要噪声源,为后期系统噪声优化及异响处理提供理论及数据支撑。

This paper analyzes the work and noise mechanism of the pump gas system of the exhaust unloading type air brake diesel engine by investigating the noise of air compressor, dryer, air tanks,and finds out the noise source of the pump gas system, to provide theoretical and data support for pump gas system noise optimization and abnormal sound processing.
