An Improved CEEMDAN Time‐Domain Energy Entropy Method for the Failure Mode Identification of the Rolling Bearing

Abstract: As a key component of a mechanical system, the extraction and accurate identification of rolling bearing fault feature information are of great importance to guarantee the normal operation of the mechanical system. Aiming at that the extraction of rolling bearing fault features and traditional support vector machine parameters affects the overall accuracy of pattern classification, the improved CEEMDAN (complete ensemble empirical mode decomposition with adaptive noise) time-domain energy entropy-based model f… Show more

“…The time-domain characteristic values of the vibration signal were calculated and analyzed, and six dimensioned parameter indexes were selected, including absolute mean, rms value, variance, peak-peak, skewness value and steepness value, a total of 5 dimensionless parameter indexes of peak index, margin index, pulse index, waveform index and steepness index, and four frequency domain characteristic parameter indicators including center of gravity frequency, mean square frequency and frequency standard deviation were selected to form the time frequency domain fault characteristics [11][12][13][14] .…”

“…As classical signal processing methods, EEMD and CEEMDAN are often used by researchers to compare with the proposed methods. 4850 To verify the effectiveness of ICEEMDAN in fault diagnosis, the original vibration signal and the feature vectors extracted by EEMD, CEEMDAN, and ICEEMDAN are used as the input of Ghost-IRCNN model, and the accuracies are 95.33%, 97.75%, 98.27%, and 99.74% respectively. The feature vectors extracted by ICEEMDAN has the highest diagnostic accuracy in Ghost-IRCNN model, which is 4.44%, 1.99%, and 1.47% higher than the other three methods.…”
