摘要:


简述了近年来各种空间相机主镜分块方式与主镜展开机构的概念设计方案,对两个典型设计实例中展开机构的设计进行了分析对比,重点探讨了空间相机可展开系统设计中机械结构设计部分的一些方法与特点,对当前可展开机构设计的研究现状进行了总结,并给出了4m口径可展开光学系统主镜的设计要点与部分技术手段。

关键词: 空间相机, 可展开主镜, 分块方式, 驱动机构, 定位机构

Abstract:

In order to conclude the development of deployable system, two typical examples were analyzed, and the core design features were compared to discuss the design principles of deployable structures. A set of design principles and technical methods were put forward for a 4m-aperture deployable primary mirror. 

Key words: space telescope, deployable primary mirror, dividing strategy, driving mechanism, locating mechanism
