Eight rod connection type non-contact satellite platform configuration

Abstract

The invention discloses an eight rod connection type non-contact satellite platform configuration which mainly comprises a service module, a loading module and an eight rod non-contact interface module, wherein the service module, the loading module and the eight rod non-contact interface module are in non-contact connection with each other; the service module is arranged at the bottom of the configuration; the eight rod non-contact interface module is connected onto the service module; the loading module is connected with the upper part of the eight rod non-contact interface module; the loading module is equipped with quiet components such as a payload and a star sensor; interference components such as a solar array and a flywheel are mounted in the service module; the loading module is connected with the service module through the eight rod non-contact interface module comprising eight actuators arranged in an orthogonal manner, so as to completely isolate the payload from platform vibration and interference response. Through the adoption of the configuration, delicate hierarchical control can be conducted on satellites; the interference of the service module is high, so that coarse tracking control is realized; the loading module is quiet and undisturbed, so that the pointing is accurate. The configuration has the advantages that the composition is simple; the hereditability is high; all the parts are clear in interface; the modularized characteristic is obvious; collateral development is easy.

Description

technical field [0001] The invention relates to the field of aerospace technology, and more specifically relates to an eight-bar connection non-contact satellite platform configuration designed for a spacecraft with ultra-precise and ultra-stable pointing requirements. Background technique [0002] Flexible accessories, liquid sloshing, etc. are very flexible, and the problem of spacecraft flutter caused by dense low-frequency modes is becoming more and more obvious, which greatly limits the bandwidth of the control system; the periodic dynamic interference induced by moving parts such as flywheels, gyroscopes, and driving mechanisms is Constantly cause harmful vibrations to the load. With the improvement of spacecraft performance requirements, the problems of attitude control and flutter suppression caused by these factors have become the main constraints for the development of subsequent advanced spacecraft. [0003] At present, there are mainly two types of vibration iso...
