The invention relates to a large-drift-diameter rectangular sealed cabin door device of a manned spacecraft, which is particularly suitable for the manned spacecraft needing a vacuum sealing environment, and belongs to the technical field of spacecrafts. According to the rectangular sealed cabin door, the drift diameter is a rectangle with the drift diameter being 1300 mm * 1300 mm or above, compared with an existing round cabin door with the drift diameter being 850 mm, the drift diameter area is increased by two times, the cabin penetrating channel requirements of multiple astronauts and large cargo products can be met, and reliable vacuum sealing performance under one atmospheric pressure difference can be achieved. The door frame structure adopts a spherical thin-shell pressure-bearingstructure; the door body structure adopts a combined curved-surface thin-shell pressure-bearing structure with reinforcing ribs, the two have good rigidity matching performance, cooperative deformation of a sealing surface can be achieved after pressure bearing, the problem that a rectangular opening structure deforms unevenly after bearing pressure and being stressed is fully solved, and reliable sealing performance is guaranteed through a light structural configuration.

    本发明涉及一种载人航天器大通径矩形密封舱门装置,尤其适用于需要真空密封环境的载人航天器,属于航天器技术领域。本发明矩形密封舱门,通径为1300mm×1300mm以上的矩形,与现有通径850mm的圆形舱门相比,通径面积增大2倍,能够满足多名航天员和大型货物产品的穿舱通道需求,并可实现一个大气压压差下可靠的真空密封性能。其中门框结构采用球面薄壳承压结构,门体结构采用布有加强筋的组合曲面薄壳承压结构,两者具有较好的刚度匹配性能,承压后可实现密封面协同变形,充分克服矩形开口结构承压受力后的变形不均问题,以轻量化的结构构型保证可靠的密封性能。
