| 摘 要： | 基于曲梁理论和Ｂｉｏｔ－Ｓａｖａｒｔ定律提出描述超导载流线圈力学行为的一个新的理论模型。通过对边值问题基本方程的半解析求解－给出封闭形式的解析通解和数值特解，所得结果可模拟载流线圈的变形、失稳全过程，获得所有的位移，应力分布，并准确预测出线圈失稳时的临界电流值。

| Abstract: | A new theoretical model for describing mechanical behavior of the current carrying superconducting coil is presented on the basis of bending theory of curved beams and the Biot Savart law. Through the solution of the boundary value problem by the semi analytical method which gives out the closed form of general solutions and numerical particular solutions to the basic equations, the deformation and buckling process is simulated, all displacements and stresses of coil are obtained, and the critical buckling current of coil is accurately predicted. |
