Abstract: Based on the analysis of testing principle in leakage fields of wire rope faults, a series of the characteristic values of wire rope default signals are defined. Applying fuzzy method to discern the characteristic values of the wire rope signals, the evaluation accuracy of the fault status is obviously increased. Finally, the experiment results of the new method are introduced.
