The longitudinal coil of the HT 7U superconducting Tokemark device is the core component of the whole device and its structure is complicated. It is difficult to directly test the whole coil and it is necessary to perform finite element analysis on the mechanical properties during the design phase. The longitudinal field coil is simplified. The stress distribution in the straight section of the longitudinal coil under electrodynamic force is analyzed by finite element method. The stress distribution in the two-dimensional section is obtained. The superconductivity Conductor radius of the radius of the stress distribution. These results provide a reference for the design and improvement of the coil.
