| 摘 要： | 基于直杆弯曲的电磁力－变形耦合的数学模型，分析了两铁磁介质间超导直杆的自场稳定性，利用分离变量法和有限元方法，计算了初始磁场和挠动磁场，得到了超导直杆的临界电流，可以看到，由于耦合效应，单元性质较为复杂。

| Abstract: | On the basis of the mathematical model of the bending of a rod with a coupled effect of electromagnetic field and deformation, the self field stability of a superconducting rod is studied. The initial and perturbed magnetic fields are calculated numerically by finite element method, and the critical current values are obtained under certain contitions. It can be seen that the properties of the element are more complex due to the coupled effect. |
