【摘要】：高溫超導(dǎo)帶材各向異性嚴(yán)重制約了磁體臨界電流密度的提高,從而使其儲能也受到影響。主要通過有限元分析軟件對磁體建模仿真,在磁體帶材用量不變的前提下,首先以單螺線管型磁體為前提,研究不同徑高比對磁體儲能的影響,并獲取儲能最高時的最佳徑高比。在此基礎(chǔ)上,通過結(jié)構(gòu)優(yōu)化,建立二階梯結(jié)構(gòu)的磁體使儲能進(jìn)一步提高,并獲得此時儲能最大時磁體結(jié)構(gòu)所滿足的條件——即滿足θ約等于40°時。最后,通過由單一帶材到混合帶材的使用進(jìn)一步提高儲能。仿真結(jié)果表明,通過上述的結(jié)構(gòu)和帶材的優(yōu)化,磁體的儲能效率明顯提高約61%。
[Abstract]:The anisotropy of HTS tapes seriously restricts the increase of critical current density of magnets, which also affects their energy storage. Based on the finite element analysis software, the effect of different ratio of diameter to height on the energy storage of magnets is studied under the premise that the amount of magnet strip is invariable, and the single solenoid magnet is the premise. The optimum ratio of diameter to height is obtained when energy storage is the highest. On this basis, through structural optimization, a two-step structure magnet is established to further improve the energy storage, and the conditions satisfied by the magnet structure at this time when the energy storage is maximum is obtained-that is to say, the magnet structure satisfies the condition of 胃 = 40 擄. Finally, the energy storage is further improved by the use of single strip to mixed strip. The simulation results show that the energy storage efficiency of the magnet is improved by about 61% through the optimization of the structure and strip.
