strong linear correlation between some characteristic values of damage signal, the linear correlation coefficient between
mean value and root mean square characteristic value was as high as 0.98, the linear correlation coefficient between peak
factor and margin factor was as high as 0.89, and the linear correlation between waveform factor and pulse factor was as
high as 0.9. The linear correlation coefficient between wavelet energy and peak-to-peak value was higher than that
between wavelet energy and other eigenvalues and was 0.8. After principal component analysis, the feature value of the
reduced signal was reduced from 15 to 7 and the cumulative contribution rate was 99.19%, which reduced the
complexity of signal processing and retained the damage feature information. The damage signal wavelet time-frequency
graph could effectively reflect the damage degree of wire rope cross-sectional area. The larger the damage of wire rope
cross-sectional area, the darker the color of damage signal wavelet time-frequency graph. The performance of different
quantitative recognition models was different, in order from high to low: IncepRegCNN neural network > PSO-BP
neural network > BP neural network, in which IncepRegCNN neural network RMSE and MAE were reduced by more
2
than 50%, and R was increased by more than 15%. The maximum absolute error of IncepRegCNN neural network for
quantitative identification of the cross-sectional area loss of steel wire rope friction damage was 0.4%, which had a high
recognition accuracy.
Key words: steel wire rope; friction damage; wire break; neural network; quantitative identification
