The invention discloses a pressing and releasing device suitable for a flexible spacecraft. By means of fastening connection of an electric explosion bolt and matching between a spring and a T-shapedejector rod in a spring ejector rod mechanism, the functions of containing, pressing and synchronous unlocking and releasing of the flexible spacecraft are achieved, and the separation posture of theflexible spacecraft is stable; meanwhile, different satellite-rocket relative separation speeds can be obtained by changing spring parameters, and the device has the advantages of being simple in structure, small in power supply requirement and high in reliability.

    本发明公开了一种适用于柔性航天器的压紧与释放装置。本发明利用了电爆螺栓的紧固连接,以及弹簧顶杆机构中的弹簧和T型顶杆之间的配合,实现了柔性航天器的收纳压紧与同步解锁释放功能,确保柔性航天器的分离姿态稳定;同时,通过改变弹簧参数可获得不同的星箭相对分离速度,具有结构简单、供电需求小、可靠性高的优点。
