摘　　要：钢缆索材料磁弹效应的材料特性是磁弹索力传感器励磁磁场工作点优化的依据,而目前又缺少相关报道。针对此问题,以铁磁材料磁弹效应理论为指导,提出钢缆索材料磁弹效应材料特性研究的实验方案;根据缆索材料式样设计线圈,搭建实验系统,最后针对钢缆索单丝材料完成其磁弹效应的材料特性实验;结果表明:钢缆索材料磁导率随外力增加而减小,在磁化饱和区以内,随着磁场的增加其磁弹效应越强,在磁化近饱和区,磁弹效应最明显,为磁弹索力传感器励磁磁场工作点的优化提供了依据。The magneto-elastic effect characteristics of cable material are the seniority of optimizing the actuating magnetic field＇s operating point of magneto-elastic cable tension sensors.However,there is few report about it.So experimental scheme for research of cable material＇s magneto-elastic effect characteristics is proposed based on magneto-elastic effect theory of ferromagnetic material.Coils are designed according to cable material＇s shape feature.Experimental system corresponding to experimental scheme is set up.The experiment used for material characteristics research of cable material＇s magneto-elastic effect is carried out.The result indicates that the permeability decreases as force increases,and the magneto-elastic effect strengthens as the magnetic field increases before magnetization saturation area,and it reaches the strongest near the magnetization saturation area.It provides a basis for optimization of the magnetic field＇s operating point of magneto-elastic cable tension sensors.
