摘要
太阳电池阵作为航天器的主要附件,在轨运行期间经历冷热交变的复杂热环境,在结构内部产生随时间变化的温度梯度,导致结构的热变形和热致振动,对航天器的正常运行产生重要影响。文中从航天器在轨运行空间热环境分析出发,综述了太阳电池阵的热分析、结构单元热-结构分析和热稳定性分析的研究进展,探讨了太阳电池阵热-结构分析的未来发展方向。
As an important attachment of spacecraft,solar array experiences complex environment of periodic heating and cooling when traveling in orbit,and time-dependent temperature gradient is generated in its structure.It leads to thermal distortion,even thermally induced vibration,which would probably influence normal operation of the spacecraft.Thermal environment of the in-orbit spacecraft is described in this paper at first.Then,advances in thermal analysis,thermal-structural analysis of structure elements and stability analysis of solar array are summarized.Finally,the prospects of thermal-structural analysis of solar array are discussed.
