采用铅覆盖方法,对6108G型工程机械用柴油机的主要噪声源进行了识别,通过识别弄清了该柴油机的不同薄壁部件在整个发动机噪声中所占比重的大小,为低噪声发动机的设计提供了依据。
Lead coverage method was used to identify the main noise source of 6108G diesel engine. By identifying the proportion of different thin-walled components of the diesel engine in the whole engine noise, we can provide the design of low noise engine The basis.
