大口径主反射镜的轻量化方案设计

Light Weight Design of Large-diameter Mirror

随着空间探测技术的不断发展,对光学系统中大口径主镜的需求越来越迫切。本文针对大口径主镜所面临的技术难题,通过有限元的方法研究了不同减轻方式对其结构稳定性的影响,并从中选出了最优方案,为今后的实际工程应用打下了坚实的基础。

With the unceasing development of the space primary mirrors used in optical systems are in urgent need detection technology, the large-diameter To meet the challenge in the design of large-diameter primary mirrors, several different light weight schemes of large-diameter primary mirrors are compared by using the finite element method and an optimum scheme is selected among them. Thus, the solid foundation is laid for the future practical engineering application.
