Abstract

The invention provides an eight-rod-connecting type non-contact satellite platform configuration and an assembling method. The eight-rod-connecting type non-contact satellite platform configuration comprises an upper connecting plate, a lower connecting plate, four same vertical mounting force actuators and four same horizontal mounting force actuators; both the vertical mounting force actuators and the horizontal mounting force actuators are connected between the upper connecting plate and the lower connecting plate and are arranged in a circumference manner; the vertical mounting force actuators and the horizontal mounting force actuators are arranged along the same circumference in a staggered and orthorhombic manner; the vertical mounting force actuators are vertical to the horizontal mounting force actuators. The eight-rod-connecting type non-contact satellite platform configuration implements complete isolation of an effective load on platform vibration and interference response, can be applied to spacecrafts with high-resolution sensitive effective load, such as a very-high accuracy remote sensing satellite, a deep space exploration astronomical telescope and the like, and can greatly improve exploration performance of spacecrafts.

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...
