Electromagnetic butting device for micro/nano satellites capable of rotating after being butted and butting method

Abstract

The invention provides an electromagnetic butting device for micro / nano satellites capable of rotating after being butted and a butting method. The device is mounted on micro / nano satellites and leads two micro / nano satellites to be accurately butted. The device comprises an active butting mechanism and a passive butting mechanism, wherein one end of the active butting mechanism is in the shape of a horn, a permanent magnet synchronous motor and a circle of active butting teeth are arranged in the active butting mechanism, and the permanent magnet synchronous motor drives the active butting teeth to rotate; the main body of the passive butting mechanism is in the shape of a circular truncated cone which is matched with the horn-shaped port of the active butting mechanism, and a circle of passive butting teeth are arranged in the passive butting mechanism; and after the active butting mechanism and the passive butting mechanism are butted, the active butting teeth and the passive butting teeth are meshed, and when the permanent magnet synchronous motor works, the active butting mechanism and the passive butting mechanism rotate oppositely. The device provided by the invention is small in volume, light in weight and high in reliability and can be applied to micro / nano satellites so as to enable the micro / nano satellites to realize one-dimensional rotation. After multiple micro / nano satellites are freely butted and combined, configuration transformation of a combined body is realized, and splicing and superposition of an observation field are completed, thereby being favorable for realizing multi-angle earth observation of the micro / nano satellites.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a micro-nano-satellite electromagnetic docking device and a docking method that can be rotated after docking. Background technique [0002] With the rapid development of my country's aerospace industry, satellite technology has been widely used in industry, agriculture, scientific research, military and other fields. In recent years, with the characteristics of small size, low cost and short production cycle, micro-nano satellites have become The key research objects of major countries in the world, the number of micro-nano satellites launched is also increasing year by year. The space rendezvous and docking technology of large spacecraft is relatively mature, while the space rendezvous and docking technology of micro-nano satellites is still in the research stage. At present, the docking of micro-nano satellites in space has not been realized in the world. The United States an...
