| 摘 要： | 提出了一种准各向同性高工程电流密度高温超导导体的有限元模型,利用该有限元模型计算了导体在不同弯曲半径下的应变分布以及临界电流衰减程度,并对导体样品进行了弯曲实验。实验结果和仿真结果基本一致,基于该有限元模型进一步计算了导体的不同参数对弯曲半径的影响。该研究为准各向同性高工程电流密度高温超导导体在聚变磁体领域的应用提供了参考依据。

| Abstract: | In this paper, the bending characteristics of a quasi-isotropic high temperature superconductor with high engineering current density were studied. The finite element simulation model of the conductor was established, the strain distribution and critical current degradation extent of the conductor under different bending radius were calculated, and a 240 mm long sample was made, and the sample critical currents at 77 K in self-field under different bending radii were measured. Based on the finite element model, the influence of different conductor parameters on the bending radius was analyzed. This study can provide a reference for the application of quasi-isotropic high temperature superconductor conductor with high engineering current density in the field of fusion magnets. |
