Three-degree-of-freedom space simulator

Abstract

The invention discloses a three-degree-of-freedom space simulator and belongs to the field of simulating equipment in the aerospace field. The three-degree-of-freedom space simulator aims to solve the problem that space simulated test equipment is poor in universality, high in cost, complicated in mechanical structure and high in maintenance cost. The three-degree-of-freedom space simulator comprises a two-degree-of-freedom horizontally-moving part and a single-degree-of-freedom rotating part, a high-pressure gas cylinder is adopted by the supporting surface of the simulator, the supporting surface of the simulator is designed according to the air flotation principle, the horizontal movement in the horizontal XY direction of the two-degree-of-freedom horizontally-moving part is achieved through an air floating guide rail, an air floating groove, an X-axis grating ruler and a Y-axis grating ruler, and 360-degree movement in the clockwise direction and in the anticlockwise direction of the single-degree-of-freedom rotating part is achieved through a rotary shaft, a reaction flywheel and a round grating ruler. The simulator further comprises three communication controllers, wherein the three communication controller are used for acquiring the location information in the X-axis direction, the location information in the Y-axis direction, and the location information in the rotation-axis direction respectively and driving nozzles of the simulator to spray air. The three-degree-of-freedom space simulator is used for aerospace tests for simulating the micro-gravity and micro-interference environment of the outer space.

Description

technical field [0001] The invention relates to a simulation device in the aerospace field, in particular to an experimental environment device used in aerospace equipment to simulate microgravity. Background technique [0002] Before the launch of a spacecraft, ground simulation tests are required, and the test device for simulating the outer space environment plays an important role in the development of aerospace technology. [0003] The core of the realization process of the full physical simulation of the space simulator is to minimize the external disturbance on the ground and simulate its attitude movement in the weightless state. The space simulator relies on its own high-pressure gas cylinder to form an air film between the marble base and the air flotation guide rail, the marble base and the air flotation sleeve, the rotating shaft and the upper plate, and generate an upward uniform force to offset the influence of gravity. Therefore, the movement of the three dir...
