Space electromagnetic docking mechanism capable of repeatedly achieving locking/unlocking, and docking method thereof

Abstract

The invention discloses a space electromagnetic docking mechanism capable of repeatedly achieving locking/unlocking, and a docking method thereof. The docking mechanism comprises an active docking mechanism and a passive docking mechanism. The active docking mechanism is mounted on a target spacecraft. The passive docking mechanism is mounted on a tracking spacecraft. In the docking task process,energizing is conducted to enable two electromagnets to attract mutually, after the active docking mechanism and the passive docking mechanism are docked, a motor drives a driven gear structure to rotate, and thus the active docking mechanism and the passive docking mechanism are locked through a locking mechanism; and during a separating task, the driven gear structure is driven reversely by themotor firstly, unlocking is completed, then energizing is conducted to enable the two electromagnets to repel mutually, and thus separating is completed. According to the space electromagnetic dockingmechanism capable of repeatedly achieving locking/unlocking, and the docking method thereof, docking of the two spacecrafts is achieved through the electromagnetic action principle, consumption of apropellant and plume flow contamination can be avoided, the impact speed can be controlled to be zero theoretically through continuity and reversible controllability of electromagnetic force, and thuscollision-free docking between the two spacecrafts is achieved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a space electromagnetic docking mechanism capable of repeatedly realizing locking / unlocking. Background technique [0002] With the continuous exploration, development and utilization of outer space by humans, space docking technology will play a key role in the fields of spacecraft supply, repair, maintenance, and on-orbit assembly, and has become a new research hotspot in the current aerospace field. Using thrusters based on recoil to control the position and speed of spacecraft is the mainstream method of docking technology at present, and this technology is mature, reliable, and widely used in engineering practice. However, there are still two main problems with this approach. One is that the propellant dose during the docking process directly affects the working life of the spacecraft; the other is that in order to reduce the docking speed, the thrust in the opposite dir...

AI Technical Summary

Problems solved by technology

One is that the propellant dose during the docking process directly affects the working life of the spacecraft; the other is that in order to reduce the docking speed, the thrust in the opposite direction must be used to brake the tracking spacecraft, which will not only cause plume pollution, but also cause the target spacecraft to Attitude and Position Perturbations
