Abstract

A space aluminum-based mirror assembly belongs to the field of space optical remote sensing, which solves the problems of complex support structure, large space occupation, high cost, difficulty in processing and adjusting the space optical mirror, and long development cycle existing in the existing space optical mirror assembly. , The problem that the mirror surface shape is sensitive to stress. The assembly includes an aluminum-based reflector with a high light weight ratio in space and at least three high-efficiency stress-relief support seats, and at least three high-efficiency stress-relief support seats are fixed on the two long sides by non-adhesive bonding; the material of the reflector is aluminum The back of the base material is closed, and there are lightweight holes on the two long sides and two short sides respectively. The lightweight holes are processed by combining EDM with lightweight bottom holes and wire cutting; efficient stress relief Two L-shaped stress unloading grooves are provided on the supporting base, which are fully penetrated in front and back. The invention has the advantages of low difficulty in processing and adjustment, low cost, high production efficiency, short processing cycle, and little influence of stress on surface shape.

Description

technical field [0001] The invention belongs to the technical field of space optical remote sensing, and in particular relates to a space aluminum-based reflector assembly. Background technique [0002] The space optical mirror assembly is the main component of the space optical remote sensor, and its performance affects the various indicators of the space optical remote sensor. The space optics mirror assembly is mainly composed of a space optics mirror and a supporting structure. As an optical element, the space optics mirror has high requirements on the accuracy of the mirror surface shape. All are very strict, and the main factors affecting the mirror surface shape are thermal stress and assembly stress. In order to reduce the impact of stress, the space optical mirror usually adopts back support or peripheral support. However, a common feature of these two support methods is that they both use adhesive bonding to connect the space optical mirror and the support structu...
