摘要
文章介绍了真空低温环境用大口径轻量化椭圆平反镜的结构设计、轻量化设计。并针对椭圆平反镜的装卡特点、使用环境,利用有限元分析技术分析了椭圆平反镜在力载荷、温度载荷作用下的变形。根据计算结果和使用情况给出了反射镜的设计结论。
This paper discusses the structural design and lightweight design of large-aperture lightweight elliptical plane reflecting mirror used in the vacuum cryogenic environment. According to the installation features and applicationconditions,the finite element analysis is carried out to calculate the distortion of the mirror under pressure load and thermal load. It is shown that the design of the reflecting mirror is practical.
