Capturing device for space rotation non-cooperative target

Abstract

The invention discloses a capturing device for a space rotation non-cooperative target. The capturing device for the space rotation non-cooperative target comprises a chassis and capturing web claws,wherein the capturing web claws are mounted on the chassis; a motor is arranged on the chassis; and buffering mechanisms are assembled at the root connecting parts of the capturing web claws and a driving device. According to the capturing device for the space rotation non-cooperative target, through opening and closing of a spoke consisting of five tooth-claw mechanisms, the capturing of a bearhug rotation non-cooperative target is realized. When tooth claws are clsed, a fixed external envelope can be formed; and the external envelope can restrain the motion range of the non-cooperative target so that the non-cooperative target cannot escape. According to the capturing device for the space rotation non-cooperative target, the impact force acting time is prolonged by using a compression spring when a collision occurs in the capturing process so that the impact force is reduced. In addition, as an universal joint is connected with a micro switch in series, the five tooth-claw mechanismsrealize series control so that the control complexity is greatly weakened and the control reliability is improved.

Description

technical field [0001] The invention belongs to the field of capture and capture of space-rotating non-cooperative targets, and relates to a capture device for space-rotating non-cooperative targets. Background technique [0002] Due to external disturbances, most non-cooperative targets float and spin in space. Unlike cooperative targets, non-cooperative targets cannot identify capture points and therefore cannot be captured using traditional touchpoint methods. Secondly, there is relative motion between the capture device and the rotating non-cooperative target. The capture device will be subjected to shock and vibration during capture, and this vibration will be directly transmitted to the main spacecraft, which may cause the spacecraft to malfunction. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a capture device for spatially rotating non-cooperative targets, which...
