空间站实验舱柔性电池翼约束释放机构设计与验证

Design and Verification of Restraint Release Mechanism for Flexible Solar Cell Wings in Mengtian Lab Module

柔性太阳电池翼国内首次在中国空间站成功应用,是空间站系统最复杂、难度最大的机电产品之一,而约束释放机构作为柔性太阳电池翼系统的关键构成,用于实现太阳翼上升段压紧保护和在轨段解锁释放,其成败直接影响航天器任务成败。基于任务需求,本文介绍了柔性电池翼约束释放机构的构成、工作原理、详细设计以及仿真验证和在轨应用情况,分析其技术特点及关键技术。地面验证及在轨飞行试验验证了约束释放机构设计的正确性与合理性,为我国航天器多点大面积可重复压紧及解锁方面提供了一种新颖且可靠的解决方案。

The flexible solar cell wing has been successfully applied in China's Space Station for the first time.It is one of the most complex and difficult mechanical and electrical products in the space station system.As a key component of the flexible solar cell wing system,the mechanism is used to realize the protection of the flexible solar cell wings in the ascent stage andunlock andrelease the flexible solar cell wings in the orbital section.Therefore,the success of the space mission depends heavily on the proper functioning of the restraint release mechanism.Based on the task,this paper introduces the structure、principle、design、simulation and application in orbit,and analyzes the technical characteristics and key technologies.The ground verification and in-orbit flight have verified the correctness and rationality of the design for the restraint release mechanism,and provided a novel and reliable solution for the multipoint and large-area repeatable compression and unlocking for the Chinese spacecraft.
