Intermittent contact derotation method for space tumbling target based on relative ellipse configuration

Abstract

The invention discloses a space tumbling object intermittent contact derotation method based on a relative ellipse configuration, comprising: from the perspective of safety, determining the derotation contact point position based on the space tumbling target and the envelope body of a space derotation robot; The principle of the least impact on the platform determines the configuration of the manipulator of the space derotation robot; the relative elliptical configuration of the space derotation robot and the space tumbling target is determined according to the position of the derotation contact point and the configuration of the manipulator. The relative ellipse configuration determines the relative position and attitude relationship between the space derotation robot and the space tumbling target, which can make the end effector of the space derotation robot contact the target periodically under the action of the relative orbital dynamics, and apply derotation to the target. Force and derotation torque to achieve derotation to the target. The invention can maximize the use of the periodicity and hovering characteristics of the relative orbit to realize safe and effective derotation of space objects.

Description

technical field [0001] The invention relates to an intermittent contact derotation method for a space tumbling target based on a relative ellipse configuration, which belongs to the field of aerospace technology and is used for a space derotation robot to approach a space tumbling target in close contact with a space tumbling target, which is conducive to smooth on-orbit service Implementation and active removal of space debris. Background technique [0002] Since mankind entered the space age in 1957, the number of space debris has far exceeded the number of satellites in normal operation. According to statistics, as of January 2019, humans have conducted a total of about 5,500 launches, and there are 19,404 large objects in Earth orbit, including 4,972 satellites and 14,432 debris. It can be seen that among these large space objects, only about 1 / 4 are satellites, but less than 1 / 3 of them are controllable; about 1 / 5 are rocket bodies and other mission-related objects, an...
