用商用有限元程序计算了超导体的磁化强度。如果我们使用商业程序,创建复杂结构的模型是很容易的。使用这种程序计算超导体的磁化强度需要一些技术,因为商业上可用的有限元程序只针对特定的问题,如热、变形和场计算。利用有限元分析软件Ansys成功地对磁通运动和磁化过程进行了模拟。具有超导扩散势垒的多芯Nb3Sn导体中的磁通运动被形象地看作是一幅运动画面。熔剂穿过阻挡层后扩散,并穿透到每根细丝中。合理计算了Bean模型和可变JC模型的磁化曲线。
Superconductor magnetization was calculated using commercial FEM program. It is easy to create models of complex structures if we use commercial programs. Calculating superconductor magnetization using such program requires some techniques because commercially available FEM programs are made only for specific problems such as thermal, deformation and field calculation. We have successfully made a simulation of flux motion and magnetization using ANSYS. Flux motion in multi-filamentary Nb3Sn conductor with superconducting diffusion barrier was vividly seen as a motion picture. Fluxes spreads after penetrating through barrier and penetration into each filament take place. Magnetization curves of Bean model and variable Jc models were reasonably calculated.
