The annular pressure-resistant shell device comprises hemispheres at the head end and the tail end and a middle multi-section bent annular structure, and the bending radius R of the middle multi-section bent annular structure and the length L of the annular structure need to be specifically distributed according to the actual sizes such as the pressure-bearing requirement of the submersible and the total length of the submersible. The bent annular structures are spherical, and tangent planes are arranged on the two sides of each bent annular structure, so that subsequent connection of the multiple bent annular structures is facilitated. The annular pressure-resistant shell is composed of hemispheres at the head end and the tail end and a plurality of bent annular structures, and due to the structural design, structural components can be reduced, the structural weight can be reduced, and the structural welding amount of the pressure-resistant shell of the submersible can be reduced; the weight and the welding amount of the submersible pressure-resistant structure can be reduced; meanwhile, the structural stress of the diving pressure-resistant structure can be improved; and the internal minimum stress level of the diving pressure-resistant structure is effectively reduced.
本发明公开了一种适用于潜水器的环状耐压壳装置,包括首尾两端的半球和中间多段弯曲环状结构组成,所述中间多段弯曲环状结构的弯曲半径R、环状结构长度L需要根据潜水器承压要求、潜水器总长等实际尺寸进行具体分配,所述弯曲环状结构为球形,且该弯曲环状结构的两侧均设置有切面,便于后续多个弯曲环状结构连接。该环状耐压壳是由首尾两端的半球和多个弯曲环状结构构成,且该结构设计不仅可以减少结构构件、降低结构重量,而且可以减少潜水器耐压壳的结构焊接量;本发明可以减少潜水耐压结构的重量和焊接量;同时可以改善潜水耐压结构的结构应力;并有效的降低潜水耐压结构内部最小应力水平。
