摘　　要：提出了双级螺旋式重复折展锁解太阳翼,通过分析其工作原理,根据双级螺旋式重复折展锁解太阳翼设计需求,完成了其功能分析以及技术参数和结构尺寸的确定.通过双级螺旋式重复折展锁解太阳翼展开特性分析,研究了重复折展锁解太阳翼运动传递关系,建立了其展开运动特性分析模型,包括正运动学和逆运动学模型.利用仿真求解计算获取获得了太阳翼各基板展开的同步度与平面度值.仿真结果表明,所提出的双级螺旋式重复折展锁解太阳翼满足设计指标要求,为其进一步研究提供了重要理论依据.Two-stage helical repeated fold-unfold and lock-unlock solar wing is designed. Its func- tion analysis is conducted. Firstly, its working principle is analyzed. Based on the requirement of two-stage helical repeated fold-unfold and lock-unlock solar wing, technological parameters and specific structural parameters are determined. The fold-unfold and lock-unlock solar wing unfolding characteristic is analyzed. According to the transitive relation analysis of repeated fold-unfold and lock-unlock solar wing, the analysis modeling on its deploying kinetic characteristics, including for- ward kinematics and inverse kinematics, are derived. Simulation results show that plane degree andsynchronization degree of the solar wing can meet the requirements of specifications, which lays the theoretical foundation to further research the fold-unfold and lock-unlock solar wing in the future.
