Description

An electromagnetic force has an important effect on the performance of high temperature superconducting magnet. The superconducting magnet can be impregnated with composite resin in order to improve its mechanical stability. A three dimensional model was established by COMOSL finite element analysis software to analyze the electromagnetic stress and strain. The results show that the maximum stress is 1.54104 N/m2 and the maximum strain is 3.3310-7 at the edge of superconducting tapes inside the superconducting coil. The critical current of the superconducting coil was measured by experiment before and after impregnation with composite resin, respectively. The attenuation rate was calculated to be only 3%. Thus, there is no or minor damage to the superconductor coil during the impregnation. That is to say, the impregnation process of the superconducting coil with composite resin was acceptable.
