摘　　要：为保障钢丝绳运行安全,需要对钢丝绳进行定期无损检测。现有钢丝绳检测方法中,基于漏磁原理的电磁检测法是公认的最实用的检测方法。采用3D Maxwell仿真磁场信号,经过调整磁铁磁场强度、磁铁距离和提离值,验证圆周阵列检测方法,最后对钢丝绳漏磁进行动态仿真,记录运动全过程的漏磁信号。通过本论文的研究,得到了合适的钢丝绳探伤仪参数;对运动全过程的漏磁信号进行分析,可以得到Y方向漏磁信号对钢丝绳断丝的反应最为显著,为第二代探伤仪的设计提供了关键的数据参考。In order to ensure the safe wire rope operation,periodic nondestructive testing of wire rope is necessary.Among the existing testing methods of steel wire rope,the electromagnetic testing method based on magnetic flux leakage principle is acknowledged as the most practical method.3 D Maxwell is adopted to simulate magnetic field signals,after adjusting the magnetic field intensity,magnetic distance and lift value,verifying the circular array detection method,the dynamic simulation is conducted on the magnetic flux leakage of steel wire rope,and the magnetic flux leakage signals are recorded during the whole movement process.The appropriate test parameters are determined in the simulation,so as to provide data reference for the design of the second-generation wire rope flaw detector.
