Research on weak fault feature extraction of rolling bearings based on integrated ICEEMDAN-VME-MOMEDA algorithm
To address the challenge of accurately extracting weak fault features of rolling bearings under strong background noise
a novel fault feature extraction method integrating improved complete ensemble empirical mode decomposition with adaptive noise (ICEEMDAN)
variational mode extraction (VME)
and multipoint optimal minimum entropy deconvolution adjusted (MOMEDA) was proposed. The aim is to enhance the identification accuracy of weak fault characteristics.
Methods
2
Firstly
with minimum envelope entropy as the objective
the crested porcupine optimizer (CPO) algorithm was employed to optimize the white noise amplitude weight and the number of added noise ensembles for ICEEMDAN. The original vibration signal was decomposed
and the optimal intrinsic mode function (IMF) was selected based on the maximum envelope spectrum peak factor. Secondly
guided by minimum envelope entropy
CPO optimized the balancing parameter and center frequency of VME to extract the frequency band containing the most critical fault information from the optimal IMF. Then
targeting the maximum envelope spectrum peak factor
CPO optimized the filter length and fault pulse period for MOMEDA to enhance the fault features of the extracted signal. Finally
envelope demodulation analysis was performed on the enhanced signal to extract fault characteristic frequencies.
Results

Validated by a public dataset
the proposed method clearly extracted the inner race fault frequency (162.185 2 Hz) of the rolling bearing and its multiples
with interference frequencies effectively suppressed in the envelope spectrum. The outer race fault characteristic frequency (107.364 3 Hz) is also accurately identified. Compared to using ICEEMDAN or VME alone
this method more effectively highlights fault-induced impulses
significantly improves the signal-to-noise ratio
and provides a reliable basis for accurate fault type identification.
