摘　　要：基于Rina船级社的船体结构规范(2017),对一艘7800PCTC的汽车滚装船活动坡道水密舱盖支撑结构进行有限元结构强度分析;计算两种极限工况下的屈服强度和屈曲强度,分析了应力分布情况,并对不满足应力要求的结构进行优化,为该类船型的设计开发提供了技术参考。Based on the Rina structural rules 2017,a 7800PCTC Ro-Ro ship＇s reinforcement structure forwatertight cover at movable ramps is studied. The yielding and bulking strength of the hatch cover are calcu-lated under two extreme conditions. The structure that does not meet the stress requirement is optimized. Themethod in the present paper can providedguidance for the design and development of the type of ship.
