摘要

随着空间技术的飞速发展，对大尺寸反射镜的需求日益增长。本文从材料和制造技术的角度探讨了大尺寸空间反射镜的发展趋势。以1.0 m孔径技术验证钎焊反射镜为例，分析了焊片的设计与制作、连接和光学加工。此外，对1.0 m孔径技术验证钎焊镜进行了热真空试验、振动试验和抗辐射试验等环境试验，以评价其工程适用性。实验结果表明，经热真空试验和振动试验，1.0 m孔径技术验证钎焊镜面的表面形貌由0.038λ (λ=632.8 nm)变化为0.037λ和0.036λ。此外，经60Co γ射线辐射测试，钎焊镜的反射率基本保持稳定，具有良好的应用前景。

Preparation and environmental simulation tests of large-size silicon carbide brazed reflection mirrors

With the space technologies progress rapidly, demand of large-size mirrors is intensively growing. In this paper, the developing trend of large-size space mirrors was discussed from the angles of material and fabrication technology. Taking 1.0 m aperture technical validation brazed mirror as an example, the design and fabrication of segments, joining and optic machining were analyzed. In addition, the 1.0 m aperture technical validation brazed mirror was performed environmental tests including thermal-vacuum test, vibration test and anti-radiation test in order to evaluate its engineering applicability. The experimental results show that the surface figure of the 1.0 m aperture technical validation brazed mirror changed from 0.038λ (λ=632.8 nm) to 0.037λ and 0.036λ after thermo-vacuum test and vibration test. Additionally, reflectivity of the brazed mirror basically kept stable after 60Co γ-ray radiation test, indicating a brilliant application prospect.
