摘　　要：通过对空间大口径单体反射镜支撑技术发展现状及发展趋势的调研,总结了当前大口径单体空间反射镜支撑技术中较为成熟的技术路线。在此技术路线中,计量卸荷支撑是必须要攻克的一项核心难题。本文介绍了计量卸荷支撑的概念,并针对计量卸荷支撑研制过程中的关键技术进行了深入的讨论,包括支撑点数量、位置及支撑力大小的确定方法,支撑力执行单元的方案设计以及计量卸荷精度的保证方法等;通过对计量卸荷支撑研制过程中关键技术的总结,期望对我国空间大口径单体反射镜的研制提供借鉴意义。Based on the investigation of the current situation and development trend of the large aperture monolithic space-based mirror support technology, this paper summarized the relatively mature technical route in the current support technology for the large aperture monolithic space-based mirror. In this technical route, the metrology mount was a bottleneck that must be resolved. This paper introduced the concept of the metrology mount and discussed the key technologies in its development. These included methods to determine the number and position of support points, the support force, to ensure unloading accuracy, etc. Summarizing the key technologies in metrology mount development will provide reference for the development of the large aperture monolithic space-based mirror in China.
