Flexible supporting mechanism for reflector of spatial optical remote sensor

Abstract

The invention relates to a flexible supporting mechanism for a reflector of a spatial optical remote sensor. The supporting mechanism comprises a reflector frame, and a plurality of external ring bosses B that are circumferentially and uniformly distributed and connected with an external ring of the reflector frame; wherein the remote sensor is connected with the reflector frame through the external ring bosses B; radial flexible ring knots and axial flexible ring knots are arranged on the external ring bosses; each radial flexible ring knot comprises two radial flexible knots; each axial flexible ring knot comprises two axial flexible knots; the radial flexible knots can offset a radial force suffered by the reflector through elastic deformation; and the axial flexible knots can offset an axial force suffered by the reflector through the elastic deformation. With the adoption of the flexible supporting mechanism for the reflector of the spatial optical remote sensor, effects of stress and deformation of a remote sensor body on the reflector can be effectively eliminated; the difficulty of installing and adjusting of the reflector is reduced; the rigidity of the mechanism is ensured, effects of environmental factors such as temperature fluctuation and gravity on a surface shape of the reflector can be effectively reduced; and the supporting mechanism has the advantages that the supporting mechanism is high in rigidity, good in temperature adaptability, and easy to process and assemble.

Description

technical field [0001] The invention belongs to the technical field of space remote sensing, and in particular relates to a flexible support mechanism for a mirror of a space optical remote sensor. Background technique [0002] Space optical remote sensors will experience complex mechanical environment and space temperature changes such as shock, vibration and overload during rocket launch, and at the same time, the surface shape and stability of its optical system must be guaranteed. Therefore, the support mechanism of the space optical remote sensor mirror must be reasonably designed so that it can have good rigidity and temperature adaptability, and can effectively reduce the impact on the surface shape caused by changes in the external environment or deformation of its connecting parts. Therefore, it is necessary to provide a new type of flexible support mechanism for space optical remote sensor reflectors with high rigidity, good temperature adaptability, easy processin...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the flexible support mechanism of the reflector is: the flexible support mechanism eliminates the axial force of the reflector through the flexible pressing sheet, and the reflector and the reflector frame are bonded by adhesive, so it is transmitted from the remote sensor body to the reflector frame The axial deformation of the reflector may be transmitted to the reflector, which may affect the surface shape of the reflector; because the axial preload is realized through three independent flexible pressing pieces, the axial stiffness of the mechanism is difficult to guarantee
