摘要

针对敏捷光学卫星动中成像需求中的高刚度可展开太阳电池阵设计，采用高技术成熟度与产品成熟度的部组件，通过将开环机构转化为闭环机构、改变锁定结构从而转换一阶模态振型、对基板结构进行充分加强等方法，开展了基于撑杆刚化单板可展开太阳电池阵的方案设计，并基于机构学分析结果对设计方案进行优化。结果表明，可展开太阳电池阵展开过程平稳，不存在干涉，展开锁定机构锁定有效，展开时间约为4.5 s；展开锁定后太阳电池阵的一阶模态振型为扭转，基频约为6.1 Hz，满足敏捷光学卫星的需求。

Abstract

In view of the requirement of deployable solar array with high stiffness lead by dynamic imaging in agile optical satellites

a deployable solar array based on truss stiffener was established with components in high technology readiness level and product readiness level. The design of the deployable solar array involved the transition from open loop mechanism to close loop mechanism

the transformation of fundamental mode of vibration by changing the deployed structure

and sufficient reinforcement of the panel. Furthermore

the scheme was optimized via mechanism analysis. The results indicate that the deployable solar array allows a 4.5 s stable deployment without any interference

and the deployment and lock-in mechanism is feasible and stable. The fundamental mode of vibration is torsion with 6.1 Hz frequency. This deployable solar array can satisfy the requirement of agile optical satellites.
