Ultra-light low-centroid reflector flexible supporting structure of miniature space remote sensor and assembling method

Abstract

The invention relates to an ultra-light low-centroid reflector flexible supporting structure of a miniature space remote sensor and an assembling method. The objective of the invention is to solve thetechnical problem that the surface shape of a reflector is seriously affected due to the fact that a rotation center of a small-caliber ultra-light low-centroid reflector flexible supporting structure of an existing miniature space remote sensor does not coincide with the centroid of the reflector and large torque is generated. The invention provides an ultra-light low-centroid reflector flexiblesupporting structure of a miniature space remote sensor and an assembling method. The flexible supporting structure is provided with three flexible supporting units which are evenly distributed in a120-degree circumferential mode, each flexible supporting unit is provided with a flexible assembly, the extending lines of the central axes of the three flexible assemblies intersect at one point, namely a rotation center point shared by the flexible supporting structure, the intersection point coincides with the mass center O of the ultra-light reflector, and through elastic deformation of the flexible assemblies, the deformation difference between the reflector and the force bearing structure is coordinated, the reflector is prevented from generating internal stress, and the surface shape precision requirement of the reflector is reduced.

Description

technical field [0001] The invention relates to a support structure and an assembly method for a reflector of a miniature space remote sensor, in particular to a flexible support structure and an assembly method for an ultra-light low-centroid reflector of a miniature space remote sensor. Background technique [0002] Miniature space remote sensors have important scientific significance and economic value in providing distributed high-resolution space remote sensing images, greatly reducing the satellite load and improving the long-term stability and environmental adaptability of the load. The optical mirror is the core component of the optical system of the miniature remote sensor, and its installation and positioning accuracy directly affects the imaging quality of the optical system. Since the miniature remote sensor has strict requirements on the weight, it is necessary to carry out an ultra-light design for the optical mirror of the remote sensor, resulting in a decreas...
