英文摘要： The wire rope is used widely and its condition and safety directly relate to personal security and production safety. So the research on condition monitoring and safety diagnosis for wire rope is of great significance.Based on the material property of the wire rope, the relations among multi magnetic parameters(such as μj,R,Φn,Bl,Hs,Bs,Hc,Br,CM,ΔΦn) and the magnetic measurement principles are researched by the method of theory analysis,emulation and test. The sensor is designed to inspect multi magnetic parameters. The effects of each kind of wire rope damage on multi magnetic parameters are studied.The quantitative identification models of the wire rope damage(LF and LMA) based on μj,Φn,Bl,R and of the fatigue and material degradation based on Hs,Bs,Hc,Br,μj,R,Φn are set up. According as the strength theory and the above models, the residual strength calculation model is built. The magneto-elastic effect of the wire rope is researched and the load stress calculation model is built based on μj,CM,ΔΦn. At last, based on the residual strength and the load stress, the safety diagnosis model, fusing multi magnetic parameters, is built. The virtual instrument system is constructed to monitor the condition and diagnose the satety condition of wire rope, then the essential relationship between safety condition and the multi magnetic parameters is revealed. The theoretical basis and scientific method are offered for condition monitoring and safety diagnosis of wire rope.
