A Capture Device for Spatially Rotating Non-cooperative Targets

Abstract

The invention discloses a capture device for spatially rotating non-cooperative targets, which includes a chassis and a capture net claw installed on the chassis; a motor is arranged on the chassis, and the joint between the capture net claw and the driving device is assembled There is a buffer mechanism. The present invention realizes the non-cooperative goal of "bear hug" rotation by designing the opening and closing of the spokes formed by five tooth-claw mechanisms. When the prongs are closed, a fixed outer envelope can be formed that inhibits the range of motion of non-cooperative targets, making escape impossible. In the present invention, when a collision occurs during the capture process, the impact force is prolonged by compressing the spring, thereby reducing the impact force. In addition, the invention also connects the universal joint and the micro switch in series, so that the five tooth-claw mechanisms can be controlled in series, which greatly reduces the complexity of the control and improves the reliability of the control.

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...
