Abstract

Abstract: The preliminary analysis of vacuum vessel of different cross-section has been carried out with the ANSYS code. The results show that the strength of vacuum vessel of round arc cross-section is better than that of polygonal cross-section. The vacuum vessel with 8 and 16 sets of gravity support component is respectively analyzed. The distributing of gravity support components is optimized according to analysis results, thereby the thermal stress decreases during baking.

Key words: Cross-section, Gravity support, Thermal stress

摘要： 利用有限元分析软件ANSYS对不同截面的真空室做静力分析，结果表明圆弧形结构比多边形结构强度好。分别对8、16个重力支撑的真空室做静力分析，得到真空室与重力支撑连接位置的应力变化，优选了真空室重力支撑数量。优化设计了真空室与重力支撑连接位置，使其在烘烤时热应力减小。
