| Abstract: | The detection and extraction of signal transients through wavelet pac kets decomposition are studied and signal transient feature representation and e xtraction methods are proposed for automotive transmission gear fault diagnosis. The results show that the feature representation based on wavelet packets trans form is effective in showing the gearbox vibration feature and the reconstructed transients show the gear faults. |
