Description

technical field [0001] The invention relates to a suspension device for unloading with gravity, in particular to a suspension device for unloading with gravity for space lens ground microgravity simulation experiments, and belongs to the field of ground microgravity simulation experiments for space lenses. Background technique [0002] With the enlargement and complexity of space missions, 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 device required for ground microgravity simulation during the simulated assembly process of the space lens becomes more and more important. At present, the ground microgravity simulation experiments for space lenses are mainly divided into: passive gravity unloading suspension and active gravity unloading suspension. The active follow-up gravity unloading suspension...

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
