摘要
讨论了空间站大面积柔性太阳电池阵的动力学问题。针对该种太阳电池阵的结构特点，指出了动力学分析的复杂性。对国外所开展的几个有关动力学问题的工作作了简单的介绍。最后，利用解析法和有限元法分别对一个大面积柔性太阳电池阵的动态特性进行了分析和计算，并给出了初步的数值结果。
Dynamic problems of a large flexible solar array of space station were discussed in the paper. The complication about dynamic analysis connected with the structural characteristics of the solar array was pointed out. The works abroad about solar array dynamics were briefly reviewed. The vibration characteristics of a large flexible solar array were analyzed using the analytic method and the finite element method respectively. The numerical results have showed the validity of the methods.
