Abstract

Magnetic flux leakage(MFL) method is a main method of nondestructive inspection of wire rope.Use MFL method to test wire rope,the key is how to process MFL signal.Using wavelet transformation and wavelet neural networks to process the MFL testing signal,forms a perfect structure of wavelet neural network.Wire rope is detected by the perfect wavelet neural network.And then the result reaches a required accuracy of broken wires.So it is proved that this processing approach is feasible in the practical application.
