针对钢丝绳常见的断丝损伤,在利用电磁无损检测的基础上,给出了钢丝绳断丝信号的特征量获取方法。通过仿真实验表明:利用4个特征量相结合可以较好地定性和定量判定钢丝绳断丝损伤的位置和程度,以及判定内外断丝状况。 Aiming at the common wire breakage damage of wire rope, based on the use of electromagnetic non-destructive testing, the method to obtain the characteristic amount of wire breakage signal is given. The simulation results show that the combination of four features can be used to determine the position and extent of wire rope damage qualitatively and quantitatively, as well as to determine the internal and external broken wires.
