国际反质子与离子研究装置(FAIR)项目中的Super-FRS超导二极磁铁是一个大型温铁结构的超导磁体，由中国负责设计、研制和测试。为了研究超导线圈的性能和其设计的可靠性，前期研制了一个测试线圈。建立了一个基于ANSYS和OPERA 3D的三维失超模型，不仅将模拟结果和实验数据进行对比，更可以获得失超过程的更多细节。模型将环氧浸渍的超导线圈简化为各项异性连续介质。将ANSYS求解器用于瞬态传热过程的分析，OPERA 3D用于磁场计算，并采用ANSYS脚本语言(APDL)进行焦耳热的计算和保护电路方程的求解。模拟得到了温度、电压、电流随时间的变化曲线和失超传播过程。最后将模拟结果和测试线圈的测试结果进行了比较。

The prototype of superferric dipoles for Super-FRS of Facility for Antiprotons and Ion Research (FAIR) project was designed, fabricated, and tested in China. To investigate the performance of the superconducting coil, a so-called test coil was fabricated and tested in advance. A 3D model based on ANSYS and OPERA 3D was developed in parallel, not only to check if the design matches the numerical simulation, but also to study more details of quench phenomena. The model simplifies the epoxy impregnated coil into an anisotropic continuum medium. The simulation combines ANSYS solver routines for nonlinear transient thermal analysis, the OPERA 3D for magnetic field evaluation and the ANSYS script language for calculations of Joule heat and differential equations of the protection circuits. The time changes of temperature, voltage and current decay, and quench propagation during quench process were analyzed and illustrated. Finally, the test results of the test coil were demonstrated and compared with the results of simulation.
