TOWER CRANE WIRE ROPE DEFECT DETECTION TECHNOLOGY BASED ON MAGNETIC FLUX LEAKAGE DETECTION(MFLD)

This paper focuses on the damage detection system for wire ropes under the excitation of annular permanent magnets, and on this basis, conducts structural optimization and simulation research of the wire rope damage detection system. To enhance the strength of the detection signal and extend the service life of the detection unit, the positioning of the detection unit is arranged in such a way that it is not damaged by vibration or proximity, thereby ensuring the stability of the detection effect. Based on Comsol, the role of this method in excitation characteristics and magnetic flux leakage detection is studied. Furthermore, the optimized equipment is tested using numerical simulation methods to ensure that it not only meets the excitation characteristics for defects but also guarantees the extraction of magnetic flux leakage signals from the defective areas, achieving higher reliability. The research findings of this study can provide a theoretical basis for the optimal design of damage monitoring equipment for wire ropes in lifting machinery and have significant guiding importance for improving the overall performance of lifting machinery and equipment.
