摘要
The CR superconducting magnet is a dipole of the FAIR project of GSI in Germany.The quench of the strand is simulated using FEM software ANSYS.From the simulation,the quench propagation can be visualized. Programming with APDL,the value of propagation velocity of normal zone is calculated.Also the voltage increasing over time of the strand is computed and pictured.Furthermore,the Minimum Propagation Zone(MPZ)is studied. At last,the relation between the current and the propagation velocity of normal zone,and the influence of initial temperature on quench propagation are studied.
利用FEM软件ANSYS对德国GSI的FAIR项目的超导二极铁的超导线进行了失超模拟.该模拟形象地给出导线的失超过程,通过APDL编程可以得到失超传播速度,失超时导体的端电压随时间的变化.文章还进一步研究了导线的最小失超传播区域MPZ,失超段初始温度和电流对失超传播速度的影响.
