DAMPING VIBRATION ATTENUATION STRUCTURE FOR SPACE SATELLITE-BORNE INSTRUMENT

Title:

DAMPING VIBRATION ATTENUATION STRUCTURE FOR SPACE SATELLITE-BORNE INSTRUMENT

Document Type and Number:

WIPO Patent Application WO/2021/093549

Kind Code:

A1

Abstract:

A damping vibration attenuation structure for a space satellite-borne instrument, the structure comprising a supporting cylinder main body (1), damping assemblies (2) and a vibration attenuated assembly (3). The supporting cylinder main body (1) is independent of the vibration attenuated assembly (3) and is fixed to other supports in the satellite-borne instrument. The damping assemblies (2) are fixed to the supporting cylinder main body (1), and the vibration attenuated assembly (3) is located among the damping assemblies (2). Threads at the tail part of a metal damper (2-1) realize axial adjustment, such that the end part of the metal damper (2-1) is in contact with the vibration attenuated assembly (3). Three to six damping assemblies (2) are evenly distributed in the circumferential direction, and are arranged vertically in two groups. The damping vibration attenuation structure has the advantages that on the premise of not changing the stress of a key structure of a normal working condition, a vibration amplitude limiting protection effect is achieved on a cantilever, and materials used by the structure are light, free of deflation and free of contamination to space loads.
