Flexible telescopic capture mechanism with collision triggering function and method

Abstract

The invention discloses a flexible telescopic capture mechanism with a collision triggering function and a method. The flexible telescopic capture mechanism comprises an octahedral satellite platform, the octahedral satellite platform comprises an upper platform and a lower platform which are arranged symmetrically, the upper platform comprises a buffering platform and multiple buffering rods connected to the buffering platform, multiple telescopic rods are connected between the upper platform and the lower platform, a driving mechanism is connected to the telescopic rods, and flexible mechanical arms for capturing space fragments are connected to the driving mechanism. Passive capture of the space fragments can be triggered by collision to the buffering platform by the space fragments, the buffering mechanism assembled on the capture mechanism can buffer the impact force in the collision process and reduce damage to the mechanism in the collision process.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a flexible and scalable collision-triggered capture mechanism and method. Background technique [0002] The ever-increasing amount of space debris has seriously affected normal human spaceflight activities. In recent years, all major aerospace countries and international research institutions have reached a general consensus: debris mitigation alone is not enough. Even if new debris is no longer generated, the collisions between debris and debris in space, and between debris and satellites will continue, and will also produce More debris, and thus a chain reaction, must be actively removed from space debris. [0003] At this stage, the active removal of space debris mainly uses the capture device carried by the satellite to approach the space debris by controlling the maneuver of the satellite, and then adjusts the attitude of the satellite by injecting gas, and u...

AI Technical Summary

Problems solved by technology

In the process of capturing debris, this technology needs to adjust the attitude of the satellite to make it in a suitable capture position. This process requires precise and complex attitude control, which increases the difficulty of control.

In addition, during the capture process of space debris, because space debris is generally in a state of high-speed tumbling, the existing rigid capture mechanism is very easy to rigidly collide with space debris during the capture process, thereby causing damage...
