Abstract

The invention belongs to the field of simulators in the field of aerospace and relates to a wireless-transmission-based three-degree-of-freedom space simulator for solving the problem of strong disturbance in a space simulated test device. The simulator comprises a two-degree-of-freedom translation portion, a single-degree-of-freedom rotating portion and three communication controllers, wherein high-pressure gas cylinders are designed among bearing surfaces of the simulator by virtue of an air flotation principle, the two-degree-of-freedom translation portion can realize horizontal movements in X and Y directions by virtue of an air flotation guide rail, an air flotation trough, an X-axis grating ruler and a Y-axis grating ruler, and the single-degree-of-freedom rotating portion can realize the 360-degree clockwise and clockwise movements by virtue of a rotating shaft, a counteractive fly wheel and a round grating ruler; the three communication controllers are used for respectively collecting position information in the X-axis direction, the Y-axis direction and the rotating shaft direction and simultaneously driving nozzles of the simulator to blow and are communicated with an upper computer through wireless modules. The simulator is used for simulating microgravity and micro-interference environments of an outer space in an aerospace experiment.

Description

technical field [0001] The invention relates to a simulation device in the field of aerospace, in particular to an experimental environment device used in aerospace equipment to simulate microgravity and micro-interference. Background technique [0002] At present, with the vigorous development of the aerospace industry and the continuous research and development of spacecraft, space simulation experiments are an indispensable part before the spacecraft is launched into space. The results of space simulation largely depend on the simulation of space simulators Performance of micro-jamming in microgravity. At present, most space simulators use wired transmission, which brings interference to the simulator. Contents of the invention [0003] The object of the present invention is to solve the problem of relatively large interference in space simulation test equipment, and the present invention provides a three-degree-of-freedom space simulator based on wireless transmission...
