ITER TF线圈馈线系统地震动响应分析

摘要

对TF线圈馈线系统做了地震响应分析。利用ANSYS有限元软件对一个TF线圈馈线系统进行了模态分析与响应谱分析，得到了在地震载荷下的峰值响应(应力和位移)。最后，根据 ITER 磁体结构设计标准，对系统的最大Tresca应力进行了评估。结果表明，TF线圈馈线系统满足SC1抗震等级的要求。%The seismic response analysis of the TF coil feeder system is presented, and the modal analysis and response spectrum analysis about a TF coil feeder are carried out using the finite element software ANSYS. The peak response under earthquake load (stress, displacement) is obtained. Finally, according to the ITER magnet structure design standards, the maximum Tresca stress of the system is evaluated. The results show that, feeder system of TF coil meets the SC1 aseismic grade requirements.
