摘　　要：针对铁磁性薄壳圆筒在地磁场磁化作用下引起的周围磁异常问题,进行了薄壳圆筒径向感应磁场补偿方法研究。以薄壳圆筒的磁场特征为研究对象,分析了其在垂向地磁下的径向磁化特征,并提出了双层补偿绕组配置方案。通过对所提方案中绕组安匝量以及布置位置进行优化,以空间磁场最佳补偿为目标,确定了最优的补偿绕组的布置位置及安匝量。与单层补偿绕组最优方案相比,双层绕组方案在磁异常补偿方面有显著的性能提升,为同类型结构体的径向感应磁场补偿绕组配置及优化提供理论基础。Ferromagnetic thin shell cylinder will cause abnormal magnetic field in the surrounding space under the action of geomagnetic field.In this paper,the radial induction magnetic field compensation method of the ferromagnetic thin shell cylinder has been studied.The radial magnetization characteristics of the thin shell cylinder under the vertical geomagnetic field are analyzed,and the configuration scheme of double compensation windings is proposed.By optimizing the winding arrangement in the proposed scheme,the optimal winding arrangement position and ampere-turn are determined with the aim of optimum compensation of space magnetic field.Compared with the optimum scheme of single-layer compensation winding,the double-layer configuration scheme has a significant improvement in radial magnetic anomaly compensation,which provides a theoretical basis for the configuration and optimization of the radial induction magnetic field compensation windings for the similar structures.
