摘要
磁体失超是超导托卡马克装置特有的一种现象 ,为了能够让 HT-7U超导托卡马克装置主机结构设计有可靠的工程分析数据和分析方法 ,采用数值模拟方法分析了纵场突然发生失超时放电真空室上感应产生的电磁载荷大小及其分布情况 ,对真空室进行了结构有限元计算 ,获得了 HT- 7U装置真空室在纵场失超情况下的应力云图和位移云图 。
Quench of magnet is one of the special characteristics for superconducting Tokamak device. In order to accumulate some reliable engineering analysis method and data,in this paper the distribution and its magnitude of magnetic loads on the vacuum vessel due to the quench of toroidal field are analyzed firstly and the detailed stress and displacement nephograph on the basis of the finite element analysis for the structure of the vacuum vessel are obtained. The maximum stress and displacement on the vacuum vessel mainly locate in the inboard rectilinear shell.
