Wire rope is a widely used load-bearing component, and the detection of the degree of damage of the wire rope directly determines its usability. The signal obtained by the existing detection methods is weak, which hampers the quantitative detection task. Considering the original method of wire rope axial detection, this study proposes a method of radial magnetic vector used for flexible printed circuit (FPC) detection. The magnetic coupling pole model and 3-D simulation model are used to verify the feasibility of the radial detection method. The FPC board is processed, and the comparison shows that this method has a higher signal-to-noise ratio. Through the damaged wire rope detection experiment, the quantitative detection of broken wire damage is realized. Experiments show that FPC has a higher detection accuracy and is capable of quantitative detection, which provides a vital technical solution for next-generation wire rope damage detectors.

基于径向磁矢量的矿用钢丝绳柔性印刷电路检测技术

钢丝绳是一种应用广泛的承重部件，钢丝绳损坏程度的检测直接决定了它的好坏。现有检测方法获得的信号较弱，阻碍了定量检测任务。考虑到钢丝绳轴向检测的原始方法，本研究提出了一种用于柔性印刷电路（FPC）检测的径向磁矢量方法。磁耦合极模型和3-D仿真模型被用来验证径向检测方法的可行性。对FPC板进行加工，对比表明该方法具有较高的信噪比。通过钢丝绳破损检测实验，实现了断丝破损的定量检测。
