| 摘 要： | 本文应用能量平衡的基本原理, 获得了航天器在几种典型热工况中太阳帆板的能量平衡的基本方程以及宇宙空间的热辐射角系数基本方程.利用数值积分法, 得到了角系数的数值以及太阳帆板在不同的轨道所承受的最大温度波动, 在考虑这一温度效应后, 用有限元法分析计算了太阳能电池帆板的固有频率特性.计算结果表明, 航天器在空间轨道运行时, 通过阴区和阳区所产生的温度变化对太阳帆板的动力学特性影响是不容忽略的问题.

| Abstract: | The basic equations of energy equilibrium of solar panel in several typical heat environments and the equations for the space heat radiation angle coefficients are obtained py the principle of energy equilibrium. The angle coefficients and the maximum temperature fluctuation are obtained for a solar panel at different orbits by the method of numerical integration. After considering this temperature effect the intrinsic frequency characteristics of the solar panel is analysed and calculated by the finite element method. The result shows that the effect of dynamic characteristics of selsr panel of the spacecraft in orbits between shaded and sun lit parts can not be ignored. |
