Combined bracket of vibration isolation and hinge-like buffer for satellite flywheel

Abstract

The invention provides a vibration isolation and hinge-like type buffer combined bracket for a satellite flywheel. The vibration isolation and hinge-like type buffer combined bracket comprises an upper platform, six vibration isolation and hinge-like type buffer devices, adapting parts and a lower platform, wherein six bosses which are uniformly distributed are circumferentially arranged on the upper platform, and the bosses are respectively connected to the upper ends of the six vibration isolation and hinge-like type buffer devices; three groups of grooves which are uniformly distributed are circumferentially formed in the lower platform, and the adapting parts are respectively connected to both ends of each groove; each vibration isolation and hinge-like type buffer device comprises a vibration isolation assembly and a buffer assembly, and the buffer assembly is arranged on the inner side of the vibration isolation assembly. By virtue of the buffer assemblies in the vibration isolation and hinge-like type buffer combined bracket, the vibration isolation and hinge-like type buffer combined bracket can safely pass a launching powered phase, the vibration response magnification of a flywheel installation interface does not exceed required indexes, and the in-orbit vibration isolation performance of the bracket is not influenced; the vibration of the satellite flywheel in six directions is inhibited by the vibration isolation assemblies, so that the purpose of reducing the vibration response of a sensitive load mounting plate is achieved.

Description

technical field [0001] The invention relates to a flywheel bracket, in particular to a vibration isolation and hinge-like buffer combined bracket for a satellite flywheel. Background technique [0002] The accuracy of my country's satellite sensitive payloads is getting higher and higher, and the requirements for the micro-vibration environment of the platform are becoming more and more stringent. Therefore, it is particularly important to analyze and suppress the micro-vibration environment of the platform. Foreign studies have found that flywheel vibration is the main factor affecting the performance of satellite payloads. At present, the methods used for flywheel vibration control include damping, structural rigidity, vibration isolation and so on. The effect of damping and vibration reduction is only obvious at resonance; the rigidity of the structure will increase the mass of the satellite; the vibration reduction bandwidth of vibration absorption is narrow; It canno...
