Abstract

The invention provides a reflecting mirror supporting and fixing device and a flexible support thereof, which belong to the technical field of space optical remote sensors. The flexible support includes a first connecting part and a second connecting part, the first connecting part is used for connecting with the bracket frame assembly, the second connecting part is used for connecting with the lens body frame, and the first connecting part The part and the second connecting part are connected by a first flexible hinge and a second flexible hinge which are arranged orthogonally. In the axial direction, the first flexible hinge and the second flexible hinge are provided with a plurality of glue injection grooves, and the glue injection grooves are used for filling damping glue, so that the tangential direction of the flexible hinge rotation has damping. The invention realizes the flexible support for the reflection mirror, and can reduce the stress response of the reflection mirror and the supporting and fixing device in the vibrating environment, so as to avoid the structural damage caused by the vibration.

Description

technical field [0001] The invention relates to a mirror supporting and fixing device and a flexible support thereof, belonging to the technical field of space optical remote sensors. Background technique [0002] The supporting structure of the aerospace remote sensor mirror usually includes a metal bracket and at least three pressing blocks arranged on the bracket, the metal bracket is used to support the mirror, and the pressing blocks are used to fix the bracket with reflector. [0003] In aerospace remote sensors, small-aperture mirrors are generally supported by rigid, semi-flexible and flexible structures. Among them, the existing flexible support structure usually uses flexible elements to realize the flexible connection between the mirror and the frame, such as using a flexible pressing block to directly connect the mirror and the frame, or using a pressing block and a pad to be arranged between the mirror and the frame. The flexible connection between the mirror ...
