摘要

分析指出重量和变形两项技术要求不能直接衡量主反射镜性能

采用有限元法计算了双拱、双凹、弯月和平背四种形状主反对镜的自振频率

并通过它来衡量主反射镜的动态刚度

以寻求重量轻、变形小的主反射镜基体形状。

Abstract

It's pointed out that the performances of primary reflection mirrors couldn't be provedby their mass or deformation

It's supposed for them to be lightweight and little deformed while under loads.Natural frequencies of mirrors in some shapes

double-arch

double-concave

Single-arch and plain-rear

are calculated in Finite Element Method

which areused to determine if the mirrors meet their structural stiffness.
