| 摘 要： | 文中把目标场法引入到悬浮超导球体的球形线圈设计中,根据目标场法产生均匀磁场的原理,通过离散化绕组来近似处理球形线圈在超导球体和球形线圈的间隙内产生均匀磁场的电流密度分布规律。利用有限元分析和验证,在超导球体与球形线圈之间的间隙内产生了具有很好均匀性的悬浮磁场,这会明显提高超导球体悬浮的刚度和稳定性。

| Abstract: | In this paper,target field approach is introduced to applications in designs for spherical coils levitating a superconducting sphere,According to the principle of uniform magnetic field deduced from target field approach,through the discrete current distribution patterns to simulate the rule of current distribution which can produce uniform magnetic field in the gap between the superconducting sphere and spherical coils,A suspension magnetic field with good uniformity which can apparently enhance the stiffness and stability of superconducting levitation is verified by analysis by the finite element method. |
