频域特征是钢丝绳损伤定量识别的一个重要特征 .文中对钢丝绳断丝信号进行了空间域划分和小波变换下的频域特征提取 ,并用小波网络进行断丝的定量识别 .实践结果表明 :该方法能够在频域上清楚地区分噪声和损伤信号 ,提高了钢丝绳断丝检测的能力 .
Frequency domain feature is an important feature of quantitative identification of wire rope damage.In this paper, the frequency domain feature extraction of wire rope broken signal is carried out in spatial domain and wavelet transform, and the wavelet network is used to quantitatively identify the broken wire.Experimental results show that this method The ability to clearly distinguish noise and damage signals in the frequency domain increases the ability to detect wire breakage.
