| 摘 要： | 基于分布参数系统传递函数方法的基本理论,针对空间结构太阳电池阵的特殊结构形式,通过将太阳电池阵基板划分为条形单元,将基板间连接铰链副简化为均匀梁单元,并利用条形单元与梁单元公共结点间位移连续与力平衡条件,建立了空间结构太阳电池阵动力学特性分析的半解析计算模型。得到了太阳电池阵单块基板和多块组合基板的模态参数计算值,并将其计算结果与有限元结果进行了比较。

| Abstract: | Based on the theory of transfer function method of distributed parameter system, a semi-analytic model of structural dynamic characteristics for solar array is established. In this model, the solar panel is divided into some strip elements, and the joint hinge on solar array is simplified as a uniform beam element, and the strip element and the beam element are combined by displacement continuum and force equilibrium at their common nodes. Numerical results of modal characteristics for single and composed panels of certain satellite solar array are presented, and these results are compared with those of finite element method. |
