Abstract

The invention provides a three-dimensional active suspension type spacecraft microgravity stimulation device and relates to a spacecraft microgravity stimulation device. The invention solves the problem that the present spacecraft microgravity ground-based simulation method is only limited to the two-dimensional free motion of the spacecraft and cannot be adopted for finishing the motion experiment of the three-dimensional space of the spacecraft. Two Y-directional linear guide rails are horizontal and are mounted on the upper surface of a frame in parallel; a Y-directional servo platform is arranged on each of the Y-directional linear guide rails; an X-directional linear guide rail is connected between the two Y-directional servo platforms; an X-directional servo platform is arranged on the X-directional linear guide rail; a torque motor and a reel are arranged on the X-directional servo platform; an angle sensor and a laser ranging sensor are mounted on the lower end face of the X-directional servo platform; a sling hinge point is arranged on the X-directional servo platform; the upper end of the sling is wound on the reel; a plane reflector and a tension sensor are mounted on the sling from top to bottom; a ball bearing is arranged at the lower end of the sling. The three-dimensional active suspension type spacecraft microgravity stimulation device is applied to spacecraft microgravity stimulation.

Description

technical field [0001] The invention relates to a space vehicle microgravity simulation device, in particular to a three-dimensional active suspension type space vehicle microgravity simulation device. Background technique [0002] Space vehicles work in the microgravity environment of the outer space, and the outer space is different from the gravitational field on the earth's surface. When carrying out physical experiments of spacecraft on the ground, it is necessary to simulate the microgravity environment in space, that is, to apply compensation force to the spacecraft to offset the influence of surface gravity. Specifically, the motion function verification and kinematic algorithm verification of the spacecraft should be carried out during the completion of the experimental development stage, and the function of the spacecraft and the motion accuracy of the spacecraft should be tested at the final assembly yard. The above process must be completed on the ground, and th...
