An end effector capable of repeatedly grasping large space debris

Abstract

The invention discloses an end effector capable of repeatedly grabbing large-scale space debris. The end effector includes a penetrating structure, a deformation anchoring mechanism, a self-locking mechanism, a damping device and a launch recovery structure, wherein: the penetrating structure It consists of an anchor tip and an anchor body; the deformed anchoring mechanism is composed of an inclined slideway, a horizontal slideway, a barb structure, and a sleeve; the self-locking mechanism is composed of a slider, a slider spring, a switch, a switch spring, and a self-locking mechanism. Composed of a rod and a switch box; the damping device is composed of a damping spring and an anchor body base; the launch and recovery structure is composed of a launch rod, a recovery rod and an annular magnetic material. When capturing space debris, it is only necessary to identify the center of the intersection of the rotation axis and the precession axis of the large space debris as the incident point, which largely avoids the difficulty of cooperation targets caused by the precession and nutation of large space debris. capture puzzle.

Description

An end effector capable of repeatedly grabbing large space debris technical field The invention belongs to the technical field of active removal of space debris, and relates to a reusable grabbing space debris end effector for active removal of space debris. Background technique Since the launch of the first artificial earth satellite in 1957, aerospace technology has rapidly become the focus of the scientific field. With the rapid development of space technology, there are more and more "space debris". "Space debris" is the product of human space activities, including The rocket body and the satellite body that complete the mission, the fragments generated by the collision between space objects, etc. "Space debris" for in-orbit The spacecraft in operation poses a great threat, and when struck at high speed, it can cause the spacecraft to fail, disintegrate, or explode. example For example, in February 2009, the in-service US satellite Iridium 33 collided with R...

AI Technical Summary

Problems solved by technology

[0005] At present, there is no one method that can solve all debris problems. Due to the limitations of debris size, orbital height, energy consumption, identification technology, control technology, etc., any capture and deorbit removal method has its advantages and disadvantages

Some of the proposed methods are only conceptual studies, and some have not yet carried out on-orbit debris removal work although some have a high degree of technical maturity. This has nothing to do with the complexity of on-orbit debris removal (especially large space debris, If future collisions are not removed, more than several orders of magnitude of space debris will be produced) and the under-observation of non-cooperative targets has a great relationship, but at the same time it brings opportunities for the research of new capture methods and technologies, and there are constantly new The concept of debris removal and scientific problems arise. Research in this direction is of great significance and application value to ensure the safe operation of spacecraft, sustainable use of orbital space, new technology verification and space control
