Problems solved by technology

However, because the device adopts the built-in configuration of the double five-degree-of-freedom air-floor table, the large-angle maneuver test caused the size of the air-floating ball bearing in the external five-degree-of-freedom air-floor table to be too large, and formed a narrow ball ring belt air-flotation support structure , which leads to great difficulty in processing large air bearing ball bearings and poor working characteristics

Abstract

The invention discloses an eight-degree-of-freedom air flotation device based on double-ball co-ball-center stacked coupling. A load cabin is arranged on an upper layer air flotation ball. Platform cabins are arranged on a middle layer air flotation ball and a ball bowl composite piece. Through the co-ball-center stacked coupling form formed by a small air flotation ball assembly composed of the upper layer air flotation ball, the middle layer air flotation ball and the ball bowl composite piece and a large air flotation ball assembly composed of the middle layer air flotation ball, the ball bowl composite piece, a lower layer ball bowl and an air sealing plate, complete co-ball-center six-degree-of-freedom co-ball-center rotating motion of the load cabin and the platform cabins is achieved through the relative motion among the upper layer air flotation ball, the middle layer air flotation ball and the ball bowl composite piece in the small air flotation ball bearing assembly, eight-degree-of-freedom motion of a flotation table is obtained by combining an air flotation thrust bearing fixedly connected to the lower portion of an air flotation table supporting plate, and the eight-degree-of-freedom air flotation device has the advantages of simple structure, high integration degree, high reliability and the like and can be used for verification of large pendulum angle maneuveringcharacteristics and dynamic imaging.

Description

technical field [0001] The invention belongs to the field of spacecraft physical simulation, and mainly relates to an eight-degree-of-freedom air flotation device based on double-sphere common-center stacking coupling. Background technique [0002] With the gradual development of space-to-ground remote sensing tasks towards high spatial resolution, high efficiency, and high value, the pointing accuracy, stability, and agile maneuverability of satellite payloads have become important technical indicators for the completion of space missions. The flexible accessories such as large solar panels of traditional satellites and the movable parts such as flywheels, gyroscopes, and drive mechanisms are the main reasons that affect the satellite load attitude pointing accuracy, stability, and agile maneuverability. [0003] In the conventional satellite design, the payload module is fixedly connected with the platform module, and its attitude is controlled following the satellite plat...
