Wire Rope Fault Diagnosis Based on Wavelet Analysis and Support Vector Machine (SVM)

Article Preview

Abstract:

A diagnosis of corrosion failure in steel wire ropes based on wavelet and support vector machine (SVM) is investigated. Wavelet decomposition and reconstruction algorithm is used to denoise the magnetic flux leakage (MFL) signals, then peak value, trough value, peak-to-peak value and energy parameters are extracted as fault feature vectors, and a SVM classifier is designed and used to conduct the fault pattern recognition. The experimental results show that the accuracy of the SVM classification achieves to 100%.
