| Abstract: | Based on artificial neural networks technology , a new method is proposed for diesel engine fault diagnosis through vibration signal. Wavelet packet transform was adopted to extract the energy feature of the signal which reflects the feature of the engine fault, then a new improved algorithm (IBP)to diagnose the diesel engine failure. Experimentation and computer simulation shows that the proposed method is very effective. |
