摘要: The invention discloses an identification method of rolling bearing abrasion, which comprises the following steps: (1) characteristic frequencies intershaft at different working stages are computed out; (2) short time Fourier transform is carried out on a oscillation test signal to obtain spectrogram; (3) frequency range set up, and energy obtained by integration manner be calculated instant frequency; (4) actual under normal situation in respectively (5) capacity taken as baseline up threshold value, abrasion trend damage degree compared judged. can judge according energy, has characteristics online real capability measuring degree.
