本文在分析磁化段钢丝绳表面漏磁场分布的基础上,给出了一种利用电磁原理检测钢丝绳磨损和绳径缩细的无损检测装置,同时推导出基于检测信号空域频谱上的定量分析识别方法。
Based on the analysis of the leakage magnetic field distribution on the surface of wire rope in magnetized section, a nondestructive testing device for detecting wire rope wear and rope narrowing by using electromagnetic principle is presented. Meanwhile, a quantitative analysis and identification method based on the detected signal is deduced.
