摘要:
The fault vibration signal of rotating machinery usually represents an AM-FM characteristic, so demodulating vibration signal is an effective method for fault diagnosis. Hilbert transform (HT) is widely used to demodulate the monocomponent signal. Unfortunately, HT is likely to generate unexplainable negative frequencies. Therefore, the empirical AM and FM demodulation (EAD) method, instead of HT, is taken as an alternative to demodulate mono-component signal to overcome the negative frequency p ...More
