航天器新型伸展机构的设计研究

Design research of new deployment mechanism in spacecraft

由于空间飞行任务复杂性和多样性的要求,往往要求航天器具有快速变轨的能力,快速变轨机动过程中的过载,可能导致容易产生大挠度的太阳能帆板发生振颤,扭曲,最终影响姿态控制或结构。对太阳能帆板的关键部分伸展机构进行研究,通过国内外伸展机构的调研,设计了两种新型机构并分别对其的可行性进行对比,为以后的机构设计做出了相应参考。

Due to the requirement of spaceflight task complexity and diversity,spacecraft need to be able to change their orbits quickly. The overload during spacecraft quickly changing their orbits,may result in libration of the solar sailboard which can easily have large deflection. This will at last affect attitude control or structure. It rely on the research to the solar energy surfboard s essential part of deployment mechanism. Through surveying foldaway solar array both here and abroad,.Designed two kind of new mechanism and carries on their feasibility separately, ultimately made the corresponding reference for the later mechanism design.
