The invention discloses a stern door device suitable for retracting and releasing a stern chute of large boat equipment and a design method. The stern door device comprises a larboard door body structure and a starboard door body structure, and multi-connecting-rod locking bolts in the larboard door body structure and the starboard door body structure are matched with bolt seats on the ship body structure; the port door body structure and the starboard door body structure are provided with an inter-door-body sealing structure and an inter-door-body sealing groove respectively, and when the stern door device is closed, the inter-door-body sealing structure abuts against an inter-door-body sealing strip in the inter-door-body sealing groove. The design method comprises the following steps: determining the type of the stern door device; determining load input of the stern door device in various operation scenes; the push-pull force in the opening and closing process of the stern door device is calculated based on kinematics and dynamics simulation, and model selection is conducted on an executing mechanism; finite element numerical simulation is carried out based on the preliminary scheme of the stern door device, and optimization design is carried out on the stern door device. According to the invention, a large access space can be provided for large boat equipment in the stern chute retracting and releasing process, and the stern cabin section can be shielded and is weather-tight.

    本发明公开了一种适用于大型舟艇装备艉滑道收放的艉门装置及设计方法。艉门装置包括左舷门体结构、右舷门体结构,左舷门体结构、右舷门体结构内发多连杆锁紧插销与船体结构上的插销座相配合;左舷门体结构、右舷门体结构上分别设有门体间密封结构、门体间密封槽,当艉门装置关闭时,门体间密封结构抵住门体间密封槽内的门体间密封条。设计方法为:确定艉门装置型式;明确艉门装置多种作业场景下的载荷输入;基于运动学及动力学仿真计算艉门艉门装置启闭过程的推拉力,对执行机构进行选型;基于艉门装置初步方案进行有限元数值仿真,对艉门装置进行优化设计。本发明可为大型舟艇装备在艉滑道收放过程提供较大进出空间,以及艉舱段遮蔽及风雨密。
