Abstract

The invention provides an eight-bar connection type non-contact satellite platform configuration and assembly method, including: an upper connection plate, a lower connection plate, four identical vertical installation force actuators, and four identical horizontal installation force actuators ; The vertical installation force actuator and the horizontal installation force actuator are connected between the upper connection plate and the lower connection plate, and are arranged in a circle; the vertical installation force actuator and the horizontal installation force actuator are arranged staggered and orthogonally along the same circle ; The vertical installation force actuator and the horizontal installation force actuator are perpendicular to each other. The invention realizes the complete isolation of the payload from the platform vibration and interference response, and can be applied to very high-precision remote sensing satellites, deep space exploration astronomical telescopes and other spacecraft carrying high-resolution sensitive payloads, which will greatly improve the detection performance of spacecraft .

Description

technical field [0001] The present invention relates to a non-contact satellite platform configuration, in particular to an eight-bar connection type non-contact satellite platform configuration. Background technique [0002] Flexible accessories, liquid sloshing, etc. are very flexible, and the problem of spacecraft chatter 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 drive mechanisms is constantly Cause harmful vibration of 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 isolation platforms, passive and active, for the vibration of satellite flexible...
