Abstract

The invention discloses a triaxial air bearing table ultrahigh precision measuring device and a triaxial air bearing table ultrahigh precision measuring method based on tracking technology. The triaxial air bearing table ultrahigh precision measuring device comprises a triaxial air bearing table, tetrahedral prisms, a circular guide rail, a pulley, a vertical beam, a longitudinal moving table, a rotating table, two photoelectric autocollimators, and a controller. A tracking system comprising the circular guide rail, the pulley, the vertical beam, the longitudinal moving table, and the rotating table is adopted, and relative position relations between the photoelectric autocollimators and the tetrahedral prisms are adjusted according to the maneuvering range of the triaxial air bearing table, and the measuring range of the triaxial air bearing table measuring device is enlarged, and large scale dynamic measurement is realized. By adopting the circular guide rail, the pulley, the vertical beam, the longitudinal moving table, and the rotating table, second of arc level control precision is achieved, and the second of arc level high precision measurement is realized.

Description

technical field [0001] The invention relates to the technical field of satellite motion simulation, in particular to an ultra-high-precision measurement device and method for a three-axis air bearing platform based on tracking technology. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] The three-axis air bearing table is the key device for the full physical simulation of the satellite attitude control system. It is used to test the performance of the satellite control system in the full physical simulation experiment and is an important means and method in the development of space vehicles. [0004] The three-axis air bearing is built on the basis of ball bearings. The ball bearings rely on compressed air to form a high-pressure air film to float the simulated platform, simulating the operating environment of t...
