Abstract: The fatigue status of the wire ropes bended was simulated. Surface magnetic field distribution of the wire ropes was tested by metal magnetic memory technology, and the variation of magnetic field intensity was analyzed and compared. Experiment showed that stress concentration and wire rope fatigue damage could be effectively diagnosed at the early stage by magnetic memory testing, and it was significant for avoiding accident.
