摘要
HL–2M装置真空室为D型截面,双侧薄壁为全焊接结构,内环直径为2m,外环直径为5.22m,环高3.02m,真空室由内壳、外壳、加强筋以及各种形式的窗口组成。整个真空室由20个扇形段焊接而成,材料采用Inconel 625、Inconel 718与316L组合形式。运用有限元法对真空室进行了结构强度评估,通过对危险工况进行分析计算得知真空室满足工程设计要求。
HL-2M vacuum vessel is designed with a D-shaped, double thin-wall structure, which consists of inner shell, outer shell, ribs and ports. Torus inside and outside diameters are 2m and 5.22m, respectively. Torus height is 3.02m. The whole torus will be welded with 20 sectors. Inconel 625、Inconel 718 and 316L are selected for the vessel material. Finite element analyses of vacuum vessel are conducted. The results show that vacuum vessel structure can meet the design requirements of the machine.
