Abstract:

This research put forward the steel wire rope detection system for the actual need of mining hoist. The detection system by extracting the damage signal characteristic value, quantitative identification, and the least squares curve fitting was fitted on to quantificationally analyze the flaw signals.Plenty tests and experiments show that the signal analysis and processing system can implement the aim of nondestructive detection, and the results of signal analysis and processing accord with the actual faults,it is feasible in the practical application.

Key words: Wire rope, signal of magnetic flux leakage, least square method, quantitative recognition
