煤矿内燃机噪声源的分析与降噪方法

Analysis and Control Method of Noise Source for Internal Combustion Engine of Mine

产生环境噪声的原因很大一部分来源于内燃机,为降低煤矿用机械设备的噪音,介绍了内燃机在运转过程中产生噪声的各类因素,列出了内燃机主要噪声源的特点及降噪方法,并提出了控制噪声的有效措施。

The majority reason of environment noise origins from internal-combustion engine. In order to reduce the noise of mine mechanical equipment, introduces the different kinds of reasons for noise generation when the internal-combustion engine works. Gives out the main features of internal-combustion engine noise source and the noise reduction methods. And also proposes the effective measures of noise control.
