发动机噪声源识别技术的研究

Identification of Engines Noise Sources

应用神经网络 ,通过对发动机噪声试验数据的反复学习 ,实现了对发动机噪声源的识别 ,大大减少了发动机噪声试验的工作量 ,为降低和控制发动机噪声提供了准确的信息 ,也缩短了发动机的设计周期。

Applying neural network,the identigication of engine′s noise sources is realized through repeatedly learning of noise testing data,which greatly reduces the amount of testing work and provides a new effective means to the identification of engine′s noise sources.
