Abstract

The invention discloses a capture mechanism and a multi-level lead screw non-cooperative target docking mechanism, and relates to the technical field of aerospace. The mechanisms solve the problems about operation such as recognition, measurement and capture on a target under the non-cooperative situation of an existing spacecraft. According to the scheme of the capture mechanism, a first motor drives a linkage mechanism to rise to a grab portion to be in an open state, and the grab portion is driven by the linkage mechanism to rapidly fold and contract backwards. According to the scheme of the docking mechanism, the docking mechanism is composed of the capture mechanism and a telescoping mechanism, wherein the telescoping mechanism achieves stretching and contraction in the mode that a second motor drives three levels of lead screws to stretch out level by level through a bevel gear drive mechanism and a spur gear drive mechanism. The capture mechanism and the multi-level lead screw non-cooperative target docking mechanism are used for effectively capturing a long-distance jet pipe.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a capture mechanism and a multi-stage lead screw non-cooperative target docking mechanism. Background technique [0002] The rapid development of space technology has put forward new requirements and challenges for the research of spacecraft application technology. In order to expand the functions and application scope of spacecraft, various countries have carried out research on various space application technologies. Since the early 1960s, countries have launched research on space rendezvous and docking technology. The former Soviet Union and the United States first conducted a large number of space rendezvous and docking researches and successfully applied them in practice. Space rendezvous and docking can be divided into two types: cooperative target docking and non-cooperative target docking. At present, the technology of cooperative target docking is quite mature, and t...
