| Abstract: | 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 learn- ing ability. With classification and training various kind of faults of engine pump machine, get good result. |
| Keywords: | engine pump machine fault diagnosis wavelet packet neural network fuzzy distance |
