| Abstract: | According to some fault status and normal status for the axial plunger pump in pump truck,the paper collects the vibration acceleration signal at the upper part of the pump shell,makes the energy vectors obtained from all frequencies by adopting the wavelet packet energy to decompose,and undertakes the fault classification research in the Fuzzy ARTMAP neutral network,and achieves the excellent diagnosis ratio,so as to provide the theoretic reference for establishing the long-distance fault diagnosis system. |
