Abstract EN
In view of the incipient fault characteristics are difficult to be extracted from the raw bearing fault signals, an incipient bearing fault diagnosis method based on parameter-adaptive variational mode decomposition (VMD) is proposed.
The beetle antennae search (BAS) algorithm is adopted to seek for the optimal combination of the VMD parameters.
The reciprocals of the calculated kurtosis values of intrinsic mode functions (IMFs) decomposed via VMD are employed as a fitness function in the searching process.
The optimal mode number and the quadratic penalty term of VMD are adaptively set after the search.
Afterwards, a vibration signal is decomposed into a set of IMFs using the parameter-adaptive VMD, and the IMF with the maximal kurtosis value is selected as the sensitive one.
The selected IMF is further analyzed by Hilbert envelope demodulation.
The resulting envelope spectrum can show the significant fault impulse characteristics which are highly helpful to diagnose incipient bearing faults.
The kurtosis and the proportion of fault energy are introduced as the input vector of the extreme learning machine (ELM).
Comparisons have been conducted via ELM to evaluate the performance by using EMD and the fixed-parameter VMD.
The experimental results demonstrate that the proposed method is more effective in extracting the incipient bearing fault characteristics.
