【Abstract】 This paper proposes a new method for fault testing on the aeroplane engine bearing. In testing, Wavelet transformation is used to extract features of dynamic vibration information and then a RBF neural network is instructed to test bearing faults. After experiments on seven categories of faults, it is revealed that the proposed method attains a satisfactory effect.更多还原
