摘　　要：真空室是中国聚变工程实验堆(CFETR)重要的屏蔽组件和包容屏障,为提高其结构稳定性,用有限元方法对真空室核心部件进行了线性屈曲分析与几何初始缺陷非线性屈曲分析,评估了真空室结构的各项稳定性指标。结果表明,现有的真空室的设计满足屈服强度的设计要求,为后续的设计优化工作提供了重要的理论依据和参考。The vacuum vessel is an important shielding component and containment barrier for the CFETR,and in order to improve its structural stability,this paper evaluates the stability indexes of the vacuum vessel structure based on linear buckling analysis and non-linear buckling analysis of geometric initial defects for the core components of the vessel based on the finite element method.The results show that the current vessel design has satisfied the yield strength as the primary design requirement,which provides an important theoretical basis for the subsequent design optimization.
