A follow-up gravity unloading suspension device

Abstract

The invention discloses a follow-up gravity unloading suspension device, which belongs to the field of space lens ground microgravity simulation experiments. The present invention includes a two-degree-of-freedom suspension bracket and an adjustable suspension device. The two-degree-of-freedom suspension bracket includes a suspension bracket, a horizontal rotation guide rail and a horizontal sliding guide rail. The adjustable suspension device includes a fixed pulley, a movable pulley, a connecting rope, a counterweight and a space lens. According to the motion process of assembling and splicing simulated on the ground of the space lens, the counterweight unloaded by gravity moves along the horizontal rotating guide rail and the horizontal sliding guide rail to achieve two degrees of freedom movement in the horizontal direction, with a large range of motion, which is suitable for the assembly process, and can be unloaded by gravity. With high precision, the effect of microgravity simulation is closer to the real state of on-orbit assembly of space mirrors. The invention can meet the microgravity simulation requirements of space lenses with different numbers of gravity unloading points and different gravity positions, can adapt to space lenses of different sizes, can follow the assembly and splicing process of space lenses well, and has good adaptability.

Description

technical field [0001] The invention relates to a follow-up gravity unloading suspension device, in particular to a follow-up gravity unloading suspension device used for a space lens ground microgravity simulation experiment, and belongs to the field of space lens ground microgravity simulation experiments. Background technique [0002] As space missions become larger and more complex, satellites tend to carry more and larger payloads, such as advanced large-aperture space telescopes composed of space mirrors, and their functional requirements are becoming more and more stringent. Therefore, the experimental setup required for the simulation of ground microgravity during the simulated assembly process of the space mirror becomes more and more important. At present, the ground microgravity simulation experiments for space lenses are mainly divided into: passive follow-up gravity unloading suspension and active follow-up gravity unloading suspension. Active follow-up gravity...

AI Technical Summary

Problems solved by technology

[0003] However, due to the complex movement of the space mirror assembly on the ground and the large size range, when performing the ground microgravity simulation experiment of the space mirror, the existing space mirror counterweight passive gravity unloading suspension device can usually only move along the A single fixed guide rail moves, and the control of the space lens assembly process is relatively complicated, and the gravity unloading accuracy is not high

In addition, the adaptability of the existing space lens counterweight passive gravity unloading suspension device is not good. It cannot realize the space lens to follow the assembly process and complete the assembly and splicing tasks of the complete telescope at the same time. Many problems have not been well solved. Therefore, there are still higher requirements for the microgravity simulation device in the process of ground simulation assembly and splicing of space lenses
