Composite mechanical arm-rope system mechanism used for capturing space debris

Abstract

The invention discloses a composite mechanical arm-rope system mechanism used for capturing space debris and belongs to the technical field of aerospace. The composite mechanical arm-rope system mechanism used for capturing the space debris mainly comprises a mechanical arm envelopes, a contraction rope and a closed winding drum, wherein the mechanical arm envelope consists of a mechanical arm driving motor, a mounting platform and more than three mechanical arms; the contraction rope is mounted at the tail ends of the mechanical arms; and the closed winding drum is used for contracting the rope. According to the composite mechanical arm-rope system mechanism used for capturing the space debris, by using the mechanical arm driving motors to drive the mechanical arms to realize expansion orretraction of the mechanical arm envelopes, the space sizes of the mechanical arm envelopes are adjusted; by using the large-deformation ability of the mechanical arm envelopes, the space debris withdifferent volumes is captured; and the rope or other strip-shaped flexible mediums at the tail end absorb partial collision energy. According to the composite mechanical arm-rope system mechanism used for capturing the space debris, the captured space debris does not need to provide an active docking point, the space debris in a rotating state can be captured; compared with fish spear capturing,the composite mechanical arm-rope system mechanism used for capturing the space debris has the advantage of no damage to the space debris; and compared with rope net capturing, the composite mechanical arm-rope system mechanism used for capturing the space debris has the advantages that the reverse process of executing the capturing action can release the space debris, and foldability is realizedto reduce space occupation.

Description

technical field [0001] The invention relates to a space debris capture mechanism, which belongs to the technical field of aerospace. Background technique [0002] Space orbital resources are being occupied by more and more space debris. Cleaning up space debris is of great significance to ensure the safe operation of spacecraft. Capturing space debris is currently the main link in cleaning up space debris. Among the existing capture methods, the robotic arm capture requires the target to provide an active docking point, and it is difficult to operate the rotating target. The fishing net-style capture process is irreversible, and the harpoon may damage the target and cause more debris. Therefore need a kind of capturing mode of space debris to overcome above-mentioned defect. Contents of the invention [0003] In order to overcome the deficiencies of the existing capture methods, the technical problem to be solved by a compound manipulator-tether mechanism for space debris...
