摘要: 介绍了钢丝绳探伤仪漏磁检测原理,并使用有限元分析方法分析了传感器零件的材料、钢丝绳的提离距离及断丝根数等对基于漏磁原理的钢丝绳探伤仪检测结果的影响。分析结果表明,提离距离、断丝根数等因素对探伤仪检测结果影响较大,断丝角度、深度等因素影响较小。Abstract: The paper introduced magnetic flux leakage testing principle of wire rope flaw detector, and used finite element analysis method to analyze impact factors of detection results of wire rope flaw detector based on flux leakage testing principle, the impact factors include material of sensor parts, rope lift-off distance and number of broken wires. The analysis results show that the factors of lift-off distance and the number of broken wires have large impact on detection results of wire rope flaw detector, and the factors of angle and depth of broken wires has little impact on detection results of wire rope flaw detector.
