中文摘要：

由于存在大变形、非连续和大体量等特点,对大型太阳电池阵的展开过程进行动力学仿真面临着巨大的数值困难。基于共旋坐标法和无转动自由度的板壳理论,考虑柔性电池基板的几何非线性效应与电池板之间的接触碰撞,建立大变形柔性太阳电池阵的多体动力学模型。对大型的太阳电池阵的展开的动力学过程进行数值仿真,并对该过程中的复杂的动力学现象进行分析。研究结果给出了不同驱动下电池基板的响应、应力分布特征以及基板之间的碰撞规律。此项研究不仅为空间站大型太阳电池阵的设计和优化提供了参考依据,也为其它大型可展开空间结构的仿真提供了一种多体动力学分析方法。

英文摘要：

Owing to the large deformation,non-continuity and contact/impact,the simulation for the deployment of the large scaled solar arrays is faced with great numerical difficulty. In this paper,based on the co-rotational formulation and the plate/shell theory without rotation,a multibody dynamic model of a flexible solar array is established by considering the geometrically nonlinear effect of flexible battery cell and the contact/impact between the battery plates. Then the numerical simulation of the deployment process of the large solar cell array is carried out,and the complex dynamic phenomena in the development process are analyzed. The results given by this study show the features of the response,the stress distribution and the regular pattern of the contact between the base plates. This work can be referred to design and optimize the large scaled solar arrays in the space station,and it can be easily extended to the simulation for other large scaled space structures.
