一种涉及船用高压气瓶调压设备领域的船用气瓶组固定装置及其结构变形校核方法,固定装置包含固定架,固定架包含上限位架、下限位架、底架、竖撑杆、斜撑杆、十字撑杆组和横撑杆;上限位架和下限位架分别分隔为多个上方框单元和下方框单元,下方框单元内固定有支撑板单元,上方框单元内固定有加紧板单元;气瓶的上、下瓶身处均设有夹具,夹具包含活动夹板和固定夹板;结构变形校核方法包含:对固定架和夹具进行有限元计算模型建模;施加夹具以及两种情况下固定架的载荷和边界条件;对夹具和固定架结构逐步加载求解;该固定装置及其结构变形校核方法保证整个固定装置节省占地空间,且能够满足摇摆角度和摇摆周期的环境要求。

    The invention relates to the field of marine high-pressure gas cylinder pressure regulating equipment, in particular to a marine gas cylinder group fixing device and a structural deformation checkingmethod thereof. The fixing device comprises a fixing frame, and the fixing frame comprises an upper limiting frame, a lower limiting frame, a bottom frame, a vertical supporting rod, an inclined supporting rod, a cross-shaped supporting rod set and a transverse supporting rod; the upper limiting frame and the lower limiting frame are divided into a plurality of upper square frame units and a plurality of lower square frame units respectively, supporting plate units are fixed in the lower square frame units, and tightening plate units are fixed in the upper square frame units. Clamps are arranged on the upper bottle body and the lower bottle body of a gas cylinder; each clamp comprises a movable clamping plate and a fixed clamping plate. The structural deformation checking method comprisesthe steps: carrying out finite element calculation model modeling on the fixing frame and the clamps; applying loads and boundary conditions of the clamps and the fixing frame under the two conditions; gradually loading and solving the structures of the clamps and the fixing frame. According to the fixing device and the structural deformation checking method thereof, the whole fixing device savesthe occupied space, and the environmental requirements for the swing angle and the swing period can be met.
