The invention discloses a high-stability high-speed superconducting magnetic suspension body which comprises a superconducting magnetic suspension body and a magnetic field source, and the superconducting magnetic suspension body is located above the magnetic field source. The superconducting magnetic suspension body comprises a superconducting material, a cold source and a heat insulation layer, the superconducting material is arranged below the cold source and faces the magnetic field source, and the heat insulation layer surrounds the superconducting material and the cold source; the circulating current, the circulating current center and the seed crystal point of the superconducting material are arranged in the line direction to form a configuration structure with a buffer transition effect, so that electric-magnetic-force-thermal coupling of the superconducting material at the joint of the magnetic field source module can be effectively weakened, alternating current loss, passing resistance and vibration generated when the superconducting material runs in the line direction are reduced, and the superconducting magnetic suspension body has a low-resistance aerodynamic appearance, so that reliable, stable and safe operation of a magnetic suspension system is realized.

    本发明公开一种高稳定性高速超导磁悬浮体,其包括超导磁悬浮体与磁场源,超导磁悬浮体位于磁场源的上方;所述的超导磁悬浮体包括超导材料、冷源与绝热层,所述的超导材料设置在冷源下方且面向磁场源,所述绝热层将超导材料和冷源包围在内;所述的超导材料的环流、环流中心与籽晶点沿线路方向排布成具有缓冲过渡效果的位形结构,可以有效减弱超导材料在磁场源模组连接处的电‑磁‑力‑热耦合,降低超导材料沿线路方向运行时产生的交流损耗、通过阻力及振动,同时,使超导磁悬浮体具有低阻的空气动力学外形,从而实现磁悬浮系统可靠、平稳、安全运行。
