Space rolling target intermittent contact type racemization method based on relative ellipse configuration

Abstract

The invention discloses a space rolling target intermittent contact type racemization method based on a relative ellipse configuration, which comprises the following steps: starting from a safety angle, determining a racemization contact point position based on a space rolling target and an envelope body of a space racemization robot; determining the mechanical arm configuration of the space racemization robot according to the principle that the influence on the platform is minimum; and determining the relative elliptical configuration of the space racemization robot and the space rolling target according to the racemization contact point position and the mechanical arm configuration. The relative elliptical configuration determines the relative position and attitude relationship between the space racemization robot and the space rolling target, so that an end effector of the space racemization robot can periodically contact the target under the action of relative orbit dynamics to apply racemization force and racemization torque to the target, thereby realizing racemization of the target. According to the method, the periodicity and hovering characteristics of the relative orbit can be utilized to the maximum extent, and safe and effective racemization of the space target is achieved.

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...
