The invention provides a space embedded electromagnetic docking mechanism based on a claw and pawl teeth, and belongs to the technical field of rendezvous and docking of spacecrafts and on-orbit service. The mechanism comprises an electromagnetic device, a locking device and a pose control system; according to the mechanism, the relative position and posture of the two spacecrafts are adjusted through electromagnetic force / electromagnetic torque, flexible soft butt joint with the relative speed of zero of the two spacecrafts can be achieved during butt joint, mechanical locking of the two spacecrafts is achieved in the modes of claw locking, pawl tooth embedding and recess convex point limiting after butt joint, and the unlocking process is the reverse process of butt joint; and the space embedded electromagnetic docking mechanism based on a claw and pawl teeth avoids the inherent problems of fuel consumption, plume pollution, large impact force, no control on a docking tail section and the like of a traditional thruster docking mode, and has the advantages of non-contact, continuity, reversibility, synchronous control capability, simple structure, high reliability, repeatable work, easiness in system integration and the like.
Description
technical field [0001] The invention relates to the technical field of spacecraft rendezvous and docking and on-orbit service, in particular to a space-embedded electromagnetic docking mechanism based on claws and pawl teeth. Background technique [0002] As an important aerospace technology, on-orbit service technology is of great significance in realizing on-orbit maintenance, on-orbit assembly, and on-orbit refueling. The traditional on-orbit docking method of spacecraft relies on propellant, which is prone to collision during the docking process, and the consumption of propellant will shorten the service life of the spacecraft, and there are problems such as plume pollution and impact load. Space electromagnetic docking refers to the technology in which two spacecraft use electromagnetic force / torque to adjust their relative position and attitude, and finally connect them structurally as a whole. Different from traditional docking technology, electromagnetic docking tec...
