摘 要：
绕制了一个小型高温超导磁体,并应用光纤布拉格光栅传感器测量了该磁体在不同电流值下的应变情况,同时根据该磁体实物建立了一个超导磁体的应力、应变数值模型,并应用仿真的方法得到了磁体在相应的电流情况下的应变值,经对比此仿真结果与应变的测量结果基本一致,表明光纤布拉格光栅传感器可以应用于高温超导磁体的应力、应变研究.

摘 要：
Stress and strain are one of the sophisticated problems in superconducting magnet system.Although some simulation can be done to predict its performance,great concerns are taken about the real action.In this paper the performances of the Fiber-Bragg Grating are investigated in liquid nitrogen temperature and are applied to measure the strain in the superconducting magnet.The experiment result agrees well with simulation result.
