大口径反射镜几种轻量化孔结构形式的分析

Analysis of structural forms of lightweight hole for heavy caliber mirror

针对某空间相机的主反射镜 ,根据目前的光学器件的加工工艺性 ,利用 CAD技术对反射镜镜体进行有限元建模 ,分析了反射镜的几种轻量化孔的结构形式对镜体动、静态刚度的影响 。

Aiming at the main mirror of certain space camera, the paper analyzes the effect of several structural forms of lightweight hole on dynamic and static rigidity of mirror itself. According to processing method of optical instruments, CAD technology is adopted to set up FEM model of mirror body and then the best structural form of lightweight hole in mirror is optimized.[WT5HZ]
