摘要：

作为真空室的重要部件，支撑筋板既需要支撑真空室双层壳体，又需要支撑中子屏蔽层。在实际工作中，支撑筋板必须满足运行时的各项强度要求。分析了真空室结构特点，以及真空室支撑筋板的平面布局与结构要求。运用CATIA软件设计了支撑筋板，并在ANSYS Workbench环境下对其作了有限元分析，得到支撑筋板在真空室内工况下的强度应力云图和应变云图。结果分析表明，支撑筋板的结构和强度均满足设计要求，很好地保证了ITER真空室的正常运行。

关键词: Vacuum vessel, Supporting rib, Strength, Finite element analysis

Abstract:

As an important part of vacuum vessel, supporting rib not only supports double layer shell, but also supports neutron shielding layer. It must meet all strength requirement from them in practice. Vacuum vessel structure feature, supporting rib layout and structure requirement were analyzed. Supporting rib was designed with CATIA. Its strength stress nephogram and deformation nephogram were obtained with finite element analysis under the ANSYS Workbench environment. From the result, supporting rib structure and stress can meet the design requirement, so as to assure its normal working in ITER vacuum vessel.

Key words: Vacuum vessel, Supporting rib, Strength, Finite element analysis
