ITER校正场超导馈线系统地震分析

摘要

By using ANSYS,the finite element model of dynamic analysis for feeders was made,dynamic responses of the structure were obtained by means of the seismic response spectrum method.The results indicate that the structural of feeders are reliable,and it can meet the requirements of the design specifications of feeders.The influence of the support gaps on the seismic results of feeders was also researched.It indicates that the gaps should be fully considered in the seismic analysis of feeders.%通过ANSYS建立校正场磁体馈线动力学分析有限元模型,利用反应谱法对馈线进行地震分析,获取馈线在地震载荷下的动力响应情况.分析结果表明,现有馈线结构设计可满足馈线地震要求.同时研究了支撑间隙对地震分析的影响,结果表明,馈线地震分析需要充分考虑支承间隙的影响.
