摘　　要：随着超导技术的发展,大容量、高场强的高温超导磁体已成为未来超导磁体的主要发展方向。文中以10MJ高温超导环形磁体为研究对象,以磁体的总用线量为优化目标,采用二代YBCO带材进行了环形磁体的电磁优化设计,利用遗传算法和有限元建模获得了磁体的最小总用线量,分析了在满足磁体储能量的情况下,线圈的内直径和线圈个数对环形磁体临界电流、总用线量的影响。With the development of superconducting technology,HTS magnets with large storage energy and high magnetic field have become the future developing direction of HTS magnets. In this paper,a 10 MJ HTS toroidal magnet was chosen as the research target,and the optimization goal was to minimize the total length of HTS tapes. Electromagnetic optimal design of the toroidal magnet was carried out using 2G-YBCO tapes to get the least length of HTS tapes based on genetic algorithm and FEM modeling. Then,effects of the inner diameter and number of the coils on the critical current and the total length of tapes were analyzed under the premise that the storage energy was satisfied.
