摘要

摘要: 为研究重复折展锁解式太阳翼展开力学特性，针对其有根树链式拓扑结构特点，依据一阶模态刚度分析假设模型，由Jourdain变分原理建立太阳翼树形柔性多体系统动力学理论模型；结合太阳翼关节铰机构运动规律，采用单向递推组集建模方法构建太阳翼展开过程正逆混合动力学模型；基于重复折展锁解式太阳翼结构参数和物理性能参数进行数值仿真，研究蜂窝夹层复合式基板柔性结构对太阳翼展开力学规律的影响，得到太阳翼各基板质心运动规律及其展开过程所需施加的驱动力矩. 所得结果可较好地预测太阳翼展开过程的动态行为，为其后续工程应用提供依据.

Abstract: This paper presents the dynamic characteristics of repeated fold-unfold and lock-unlock solar array, which is in a topological tree configuration. According to the first modal stiffness analysis, assumptions about solar array multi-body system are proposed. Deduced from Jourdain variation principle, dynamic model of solar array flexible multi-body system is built. Furthermore, the forward-inverse mixed dynamic model is established through forward recursive formulation and motion law of solar array hinges. In order to study the impact of flexible structures on solar array deployment, the motion parameters of solar array panels, such as rotation angle, angular velocity and angular acceleration, are obtained from numerical simulation, which is based on the structure and physical parameters of repeated fold-unfold and lock-unlock solar array prototype. The results can well predict dynamic behaviors of solar array during its deploying process. In conclusion, this study has laid a foundation for subsequent engineering applications of repeated fold-unfold and lock-unlock solar array.
