Flexible supporting structure for space camera reflector

Abstract

The invention discloses a flexible supporting structure for a space camera reflector, belongs to the technical field of space optical remote sensing, and aims to solve a precision problem caused by environment temperature change of the reflector under the effect of gravity, so that the component assembling and detection time is shortened. The flexible supporting structure comprises a flexible mirror seat and a flexible adapter which are arranged coaxially, wherein the flexible mirror seat at least comprises an annular flexible link, and an inner ring flexible groove and an outer ring flexible groove are formed in the flexible link from an upper end face to a lower end face; the inner ring surface of the flexible link is fixedly connected with the outer cylindrical surface of a cylinder boss on the back of the reflector; the flexible adapter at least comprises an annular main body, a plurality of arc-shaped bulges uniformly distributed on the circumference of the upper end face edge of the annular main body and a plurality of fixed bodies which are peripherally uniformly distributed on the upper end face of the annular main body; the fixed bodies and the arc-shaped bulges are arranged in a staggered mode; the flexible link and the flexible adapter are arranged coaxially and are fixedly connected through the fixed bodies; and the maximum outer circumference size of the flexible adapter is smaller than the outer diameter of the reflector.

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. car air [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, flex...
