摘　　要：针对22.5°真空室扇形模型,建立CFETR真空室在等离子体大破裂工况下的有限元分析模型。通过仿真计算得到真空室在等离子体破裂工况下的涡流分布、电磁力分布,并将电磁载荷导入结构场,分析真空室不同PS段的应力、形变等结果。计算得到最大薄膜弯曲应力位于PS1段,约53.9MPa,远小于许用应力值。结果表明,真空室设计满足等离子体破裂工况下的结构强度要求。In this paper,based on the model of the 22.5°vacuum vessel,a finite element analysis model of the CFETR vacuum vessel under the condition of plasma major disruption is established.Through simulation calculation,the eddy current and electromagnetic force distribution of the vacuum vessel under major disruption working conditions are obtained,and the electromagnetic load is introduced into the structure field.The stress and deformation of the different PS sections of the vacuum vessel are analyzed.The calculated maximum film bending stress is in the first section,about 53.9MPa,which is far less than the allowable stress value.The results show that the design of the vacuum vessel meets the structural strength requirements under plasma major disruption conditions.
