| 摘 要： | EAST是一个全超导磁体系统的托卡马克实验装置，超导纵场和极向场磁体工作在4K温区下。在磁体和其它发热部件之间布置有冷屏系统，以减少作用到所有低温冷质部件上的热载，将其保持在最低水平。该系统包括真空室冷屏(内冷屏)和外真空杜瓦冷屏(外冷屏)两部分。在分析了冷屏低温运行时所受热应力以及等离子体破裂时所受电磁载荷的基础上，运用大型有限元分析程序NASTRAN，对其不同载荷状况进行了数值计算，为其结构设计与优化提供了理论依据。

| Abstract: | The EAST is a tokamak with superconducting toroidal and poloidal magnets operating at 4 K. In order to reduce the thermal load applied to surfaces of all cryogenically cooled components and keep the heat load of the cryogenic system minimal, a continuous radiation shield system located between the magnet system and the warm components is adopted. The EAST thermal shield system consists of vacuum vessel thermal shield and cryostat thermal shield. The NASTRAN finite element software was employed to calculate different load conditions of the thermal shield after analyzing the thermal stress in operation and electromagnetic forces under plasma disruptions for optimization design of the structure. |
