摘要(Abstract):

提出了利用小波包分解、神经网络和模糊诊断的方法进行发动机泵机组故障诊断;运用小波包频带能量分解,可以在不丢失振动信息的情况下降低信号的维数,提高神经网络的识别能力;运用了神经网络使故障诊断具有自适应、自学习能力,对发动机泵机组的各类故障进行分类和训练,得到了满意的效果。
Fault diagnosis of engine pump machine was carried out using wavelet packet decompose,neural network and fuzzy distance.Making use of wavelet packet decompose,it can improve the capacity of discernment in neural network without losing any vibration signal in reducing dimension of signal.The fault diagnose based on neural network have self fit in with,self learning ability.With classification and training various kind of faults of engine pump machine,get good result.
