In wire rope test,an important characteristic is to identify the features of wire rope flaw signals in frequency domain.Based on wavelet transform techniques,a new demarcation method in space domain and a new frequency feature extractive method for local wire rope flaw signals are proposed in the paper.Furthermore,the types of wire rope flaws can also be identified by the wavelet network quantitatively.The experimental results show that the proposed method can clearly distinct the noise and flaws in wire rope flaw signals.Using proposed method in this paper,the performance of wire rope flaw detective instrumentation can remarkably improved.
