Fault detection from the vibration measurement data of rotating machinery is significant for avoiding serious accidents. However, non-stationary vibration signal with a large amount of noise makes this task challenging. Multiwavelet not only owns the

The vibration signal of a gearbox carries the signature of the fault in the gears. As such early fault detection of the gearbox is possible by analyzing the vibration signal using different signal processing techniques. Time synchronous averaging can

Demodulation is an important issue in gearbox fault detection. Non-stationary modulating signals increase difficulties of demodulation. Though wavelet packet transform has better time–frequency localisation, because of the existence of meshing freq
