A B-type cabin air dome with an energy absorption connecting device is characterized in that an air dome part of a B-type cabin extends out of an upper deck, the air dome part is provided with a top plate, a deck longitudinal girder is fixed on the lower surface of the top plate, and an energy absorption connecting piece is fixed below the deck longitudinal girder. A main body of the energy absorption connecting piece is integrally in a W shape, the W-shaped main body lies down, an opening of the lying main body is far away from the air dome, an upper wing plate, a lower wing plate, two first grooves on the same side and a second groove on the different side are formed, the bottoms of the first grooves and the second groove are in circular arc shapes, the two first grooves are filled with first energy absorption rubber, and the two second grooves are filled with second energy absorption rubber. And second energy-absorbing rubber is fixed in the second groove. And the upper wing plate and the lower wing plate of the main body are respectively connected with a deck longitudinal girder and an upper deck hatch enclosure bulkhead through bolts. Structural damage caused by collision between an air dome structure and an upper-layer deck structure is effectively avoided, the tension and compression resistance of the flexible connecting steel plate is improved, transverse loads are evenly applied to the connecting bolts, and therefore the safety of the connecting device is improved.

    一种带有吸能连接装置的B型舱气穹,B型舱的气穹顶部伸出上甲板,气穹顶部带有顶板,顶板下表面固定有甲板纵桁材,甲板纵桁材下方固定有吸能连接件。吸能连接件的主体整体呈“W”型,“W”型主体躺倒放置,躺倒后的主体开口远离气穹,其形成上、下两个翼板、两个同侧第一凹槽、一个异侧第二凹槽,第一凹槽与第二凹槽底部均呈圆弧形,两个第一凹槽内填充有第一吸能橡胶,第二凹槽内固定有第二吸能橡胶。主体上、下两个翼板分别通过螺栓与甲板纵桁材、上甲板舱口围壁连接。本发明有效避免了气穹结构与上层甲板结构发生碰撞而导致的结构破坏,提高柔性连接钢板的抗拉压能力,使横向载荷均匀的施加在连接螺栓上,从而提高了连接装置的安全性。
