A flexible support structure for a space camera mirror

Abstract

A space camera reflector flexible support structure belongs to the field of space optical remote sensing technology, and aims to solve the precision problem of the reflector caused by gravity and environmental temperature changes, and shorten the assembly and detection time of components. The present invention includes a coaxially arranged flexible mirror base and a flexible adapter; the flexible mirror base at least includes an annular flexible link, and the flexible link is provided with an inner ring flexible groove and an outer ring flexible groove from the upper end to the lower end surface; the inner ring flexible groove of the flexible link The outer cylindrical surface of the circular surface and the cylindrical boss on the back of the reflector is fixedly connected; the flexible adapter at least includes a circular main body, a plurality of arc-shaped protrusions uniformly distributed on the edge of the upper end surface of the circular main body, and the circumference is uniformly distributed on the circular main body Multiple fixed bodies, multiple fixed bodies and multiple arc-shaped protrusions on the end face are arranged alternately, the flexible link and the flexible adapter are coaxially arranged and fixedly connected through the fixed body, and the maximum outer circumference of the flexible adapter is smaller than that of the reflector outside diameter.

Description

technical field [0001] The invention belongs to the technical field of space optical remote sensing, and in particular relates to a flexible support structure of a space camera reflector. Background technique [0002] The installation accuracy and surface shape accuracy of the reflector in the space remote sensor directly affect the imaging quality of the optical system. Therefore, high demands are placed on the supporting structure of the mirror. When the mirror diameter is large, its thermal stability is not ideal in the complex space thermal environment. Therefore, designing a mirror support mechanism with high specific stiffness and strong thermal adaptability is one of the key technologies for high-resolution space remote sensors. [0003] The Chinese patent with the publication number CN102262281A discloses a technical scheme of a flexible support mechanism called a space remote sensor reflector. Edge, outer ring flexible groove, inner ring convex pad, flexible fram...
