摘要: 国际反质子与离子大科学工程(FAIR)项目是一个大型的国际合作项目，其中Super-FRS超导二极磁体由中国科学院近代物理研究所研制。利用ADINA有限元程序对项目中的超导Super-FRS磁体线圈的失超过程进行了模拟分析。利用C程序对ADINA程序进行二次开发以便对有限元求解器的调用和载荷的控制。分析结果显示：在失超过程中产生的最大热应力为26 MPa,可能产生的声波频率在35 Hz左右。Abstract: The super fragment separator (Super-FRS) of the FAIR-project (facility for antiproton and ion research) is a large international cooperation project. The quench transient thermal stress is simulated using FEM software ADINA. The simulation uses the C program for a secondary development of ADINA to control the load and call the solver. The thermal stress and the acoustic are analyzed. The results show that the maximal thermal stress is 26 MPa, and the frequency of the acoustic wave is about 35 Hz．
