【Abstract】 Vibration signal measured on cylinder head was analyzed and processed with wavelet decomposition algorithm. The energy and energy percentages of different segments in time domain on scale 1 signal were worked out. These parameters and the ART network were used to carry out the clustering of different valve train states. The results show that it can carry out the diagnosing for valve train effectively and concisely.更多还原
