涡流检测在电梯钢丝绳断丝检测中的应用

Application of Eddy Current Testing to Detection of Broken Wire of Elevator Rope

根据钢丝绳的结构特点,通过对运行中的电梯钢丝绳作受力分析,阐述了断丝对钢丝绳的影响。介绍了现有无损检测钢丝绳断丝方法漏磁法的原理。提出一种涡流无损快速检测钢丝绳断丝的方法,可以实现非接触式、快速地检测钢丝绳的断丝情况。

According to the structural characteristics of wire rope, the influence of broken wire on wire rope is expounded based on the force analysis of wire rope in operation. The principle of magnetic flux leakage method is introduced, which is the existing nondestructive testing methods for broken wires of wire ropes. A method of eddy current nondestructive and rapid detection of broken wire in wire rope is proposed, which can realize non-contact and fast detection of broken wire in wire rope.
