| Abstract: | 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. |
