摘要
针对航天器设备在轨维护的需求,并考虑航天发射时的力学性能要求,设计了一套航天维护舱门并试验验证。舱门的外形为弧形,采用加筋壁板结构。8个锥销、锥套分别安装在舱门与舱体上,锁紧螺钉将锥销、锥套连接紧固,并防止锁紧螺钉的脱落丢失。舱门与舱体还通过两个铰链相连,铰链为双连杆串联结构。舱门试验时,搭建了工装试验架以模拟舱门失重状态下的操作性能。试验结果表明,锥销、锥套连接可靠牢固,锁紧螺钉具有较好的防脱落性能,双杆铰链有利于舱门的打开和关闭,舱门操作顺畅便捷,满足使用需求。
To meet the need of on-orbit maintainability of space equipment and the requirement of mechanics during space launch, this paper presents a space maintenance door and tests it. The door is shaped of arc and designed with structure of stiffened panel. 8 cones and cups are installed on the door and cabin respectively, locking screws connect and fasten the cones and cups, and locking screws are constrained not to drop out. The door and cabin are also connected by two hinges each of which consists of two rods in series. To simulate the operability of door with zero gravity, a test stand is built. Test results show that, cones and cups are fastened reliably by locking screws, and the locking screws are constrained well not to drop out. The hinges with two rods contribute to opening of closing of the door, and the door can be operated smoothly and conveniently, meeting the demand of using.
