【摘要】：高温超导带材各向异性严重制约了磁体临界电流密度的提高,从而使其储能也受到影响。主要通过有限元分析软件对磁体建模仿真,在磁体带材用量不变的前提下,首先以单螺线管型磁体为前提,研究不同径高比对磁体储能的影响,并获取储能最高时的最佳径高比。在此基础上,通过结构优化,建立二阶梯结构的磁体使储能进一步提高,并获得此时储能最大时磁体结构所满足的条件——即满足θ约等于40°时。最后,通过由单一带材到混合带材的使用进一步提高储能。仿真结果表明,通过上述的结构和带材的优化,磁体的储能效率明显提高约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 掳. 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.
