目前钢丝绳断丝漏磁场分布规律的仿真研究主要使用有限元静态磁场仿真模型，该模型中钢丝绳与损伤检测仪器之间是相对静止状态，而现场检测时钢丝绳与损伤检测仪器之间有相对运动，导致仿真获得的漏磁场与现场检测的漏磁场存在偏差。针对上述问题，采用Ansoft Maxwell电磁仿真软件建立了钢丝绳三维动态磁场仿真模型，仿真钢丝绳与损伤检测仪器之间相对运动状态下的断丝漏磁场，分析了不同断口宽度、断丝数量及提离值对断丝轴向漏磁场峰峰值的影响规律。仿真结果表明：三维动态磁场仿真模型可以模拟钢丝绳与损伤检测仪器之间的相对运动状态，仿真计算的漏磁场含有断丝漏磁场和钢丝绳绳股漏磁场，更接近实际漏磁场；断丝轴向漏磁场峰峰值随着断口宽度的增加呈先增大后减小的趋势，断丝轴向漏磁场峰峰值变化与断丝数量呈正相关、与提离值呈负相关。通过建立三维磁偶极子模型对断丝轴向漏磁场峰峰值进行分析，验证了三维动态磁场仿真模型分析结果的正确性。

Current simulation studies on the distribution pattern of magnetic flux leakage (MFL) in broken strands of wire ropes primarily use finite element static magnetic field simulation models. In these models, the wire rope and the damage detection instrument remain relatively stationary. However, during actual field inspections, there is relative motion between the wire rope and the detection instrument, leading to deviations between the simulated and actual MFL signals. To address this issue, this study established a three-dimensional dynamic magnetic field simulation model using Ansoft Maxwell electromagnetic simulation software. The model simulated the MFL of broken wires under relative motion conditions and analyzed the effects of different break widths, numbers of broken wires, and lift-off values on the peak-to-peak axial MFL. The simulation results show that the three-dimensional dynamic magnetic field simulation model can replicate the relative motion between the wire rope and the detection instrument. The simulated MFL include both the MFL caused by broken wires and that caused by wire strands, making it more representative of actual leakage fields. The peak-to-peak axial MFL initially increases and then decreases as the break width increases. Additionally, the peak-to-peak axial MFL exhibit a positive correlation with the number of broken wires and a negative correlation with the lift-off value. The accuracy of the three-dimensional dynamic magnetic field simulation model is further validated by establishing a three-dimensional magnetic dipole model to analyze the peak-to-peak axial MFL.
