摘　　要：传统舱口盖结构设计方法下,盖板失稳临界载荷偏低,致使连接滑轮位置过密,影响舱口盖的固定性,因此对大型船舶折叠式舱口盖结构优化设计。该设计对舱口盖加筋,提升单块盖板承受载荷的能力;计算盖板受压屈曲,根据提升后的载荷值预设滚轮位置;计算载荷压力和摩擦力影响下,滚轮的承载力和轴向力,校正滚轮在折叠式舱口盖上的衔接节点。实验结果表明,与传统设计方法相比,此次提出的优化方法设计的舱口盖与导轨之间的契合度更高。由此可见,该设计满足当前大型船舶折叠式舱口盖的设计要求。Under the traditional hatch cover structure design method, the critical load of instability of the cover plate is too low, which causes the position of the connecting pulley to be too close, which affects the stability of the hatch cover.Therefore, the folding hatch cover structure of large ships is optimized. The design reinforces the hatch cover to enhance the capacity of the single cover plate to bear the load;calculate the plate buckling under compression and preset the position of the roller according to the lifted load value;calculate the bearing capacity of the roller under the influence of load pressure and friction and axial force, correct the joint of the roller on the folding hatch cover. Experimental results compared with the traditional design method, the proposed optimization method has a higher degree of fit between the designed hatch cover and the guide rail. It can be seen that the design meets the current design requirements of folding hatch covers for large ships.
