【摘要】 随着空间技术的发展,空间相机反射镜尺寸不断增大。本文简述了某空间相机的大尺寸SiC主反射镜的设计。从材料选择、反射镜支撑方式、方射镜轻量化等方面进行了分析讨论,并通过有限元分析软件对所设计主反射镜在重力载荷和温度载荷情况下的面型变化,以确定设计是否满足使用要求,为反射镜的设计提供依据。更多还原

【Abstract】 As development of space technology,dimension of space camera reflector has became augmented.This article is about the design of a space camera′s first reflector.It has discussed selecting material,mode of supporting,mode of lightweight,and analyzes the reflector′s change under gravity and temperature′s changing through special software,to confirm if the design can be used,and to provide evidence for design of reflector.更多还原
