摘　　要：为研究光纤陀螺的磁敏感性,利用三个正方形亥姆霍兹线圈构建三维匀强磁场,并分析其匀强磁场区域特性。将正方形亥姆霍兹线圈视为四段载流导线,采取分段计算然后进行矢量叠加的方法,分析了正方形亥姆霍兹线圈三维空间磁场强度及其均匀性,并给出仿真结果。最后给出了正方形亥姆霍兹线圈三维匀强磁场的结构模型及相关数据分析。To study the magnetic susceptibility of fiber-optic gyroscope, three square Helmholtz coils were used to build three-dimensional uniform magnetic field, and the characteristics of uniform magnetic field region was analyzed. Regarding square Helmholtz coil as four current-carrying conductor, three-dimensional space magnetic intensity and its uniformity of square Helmholtz coil were analyzed, and the result of simulating data were given. Lastly, the framework model and data analysis of three-dimensional uniform magnetic field of three square Helmholtz coils were presented.
