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, large capacity, high field strength high temperature superconducting magnet has become the main development direction of future superconducting magnet. In this paper, the 10MJ high temperature superconducting toroidal magnet is taken as the research object, the total amount of magnet used is optimized, and the second generation of YBCO strip is used to optimize the electromagnetic design of the toroidal magnet. The genetic algorithm and finite element method The minimum total amount of the line, the analysis of the magnetic energy stored in the case, the coil diameter and the number of coils on the ring magnet critical current, the total amount of wire.
