The invention discloses a space debris cleaning mechanism based on electromagnetic ejection and a debris cleaning method, and relates to the technical field of spacecraft control research. Flexible paws are symmetrically installed on the two side faces of a service spacecraft respectively, the flexible paws are connected with corresponding spinning wheels arranged on brushless motors through ropes, and meanwhile, the space debris cleaning mechanism and the space debris cleaning method based on electromagnetic ejection are arranged on the service spacecraft. The electromagnetic coils are oppositely arranged on the side wall of the flexible gripper and the inner side wall of the service spacecraft corresponding to the flexible gripper, when the flexible gripper is used, currents of the two oppositely-arranged electromagnetic coils eject the flexible gripper to the space debris position in the same direction, and meanwhile the flexible gripper is ejected to the space debris position. The brushless motor generates different resistances according to the direction of the debris, so that the spinning wheel rotates the rope to stretch the flexible gripper to the space debris, then the steering engine and the electromagnet arranged on the flexible gripper attract and catch the space debris, and the problems that a spring is not easy to control and unstable in the using process are solved; and when debris in the space is captured, the efficiency is high, and high-quality removal of the debris in the cosmic space can be guaranteed.

    本发明公开了一种基于电磁弹射的空间碎片清理机构及碎片清理方法,涉及航天器控制研究技术领域,本发明通过在服务航天器的两侧面分别对称安装柔性手爪,并将柔性手爪通过绳索与设置在无刷电机上对应的纺车轮相连,同时,在柔性手爪的侧壁和与之对应的服务航天器的内侧壁相对设置电磁线圈,在使用时,相对设置的两个电磁线圈电流同向将柔性手爪弹射至空间碎片处,同时,无刷电机根据碎片方位产生不同的阻力使纺车轮转动绳索拉伸柔性手爪至空间碎片处,而后让柔性手爪上设置的舵机和电磁铁对空间碎片进行吸附和抓捕,避免了弹簧在使用过程中的不易控制且不稳定的难题,在对于空间中的碎片进行抓捕时效率高,可保证在宇宙空间中对碎片的高质量清除。
