Abstract

To guarantee personal and property security, the operational status of wire ropes need to real time inspection.in this study , the static magnetic field of wire rope with different broken wires width was analyzed and calculated using finite element method, and the software named Ansoft Maxwell is used to model and simulate as a tool, in experiment , the magnetic flux leakage (MFL) method is used to detect the typical defects, wavelet transform was used to eliminate background noise and to detect singularity. Wave width and peak-to-peak value as characteristic index to measure the fault signal. Simulation results indicate the leakage magnetic field components has showed growth trend with increasing fault width, Similarly, the experiment results show that the peak-to-peak values and wave width of the MFL signal increase and peak-to-peak value increases quickly compared with wave width. The results of this study have significant implications for quantitative measurement of broken wires defect detection of wire rope.
