Abstract

The invention provides an end effector for active soft capture of space debris, which belongs to the field of active removal of space debris. The top end cover of the present invention is installed on the upper part of the supporting shell, and the installation interface is installed on the lower part of the supporting shell so that the supporting and protecting device forms an upper cavity and a lower cavity, the locking claw locking and limiting device is fixedly connected on the supporting shell, and the driving mechanism is installed In the lower cavity of the support and protection device, the transmission mechanism is installed in the upper cavity of the support and protection device. The drive mechanism and the transmission mechanism are connected through flanges, and the upper end of the catch claw is fixedly connected to the transmission mechanism. control unit system connection. The invention has the characteristics of simple structure of the capture claw and large capture tolerance; it can be rigidly connected with various derotation devices on various space manipulators, and can be applied in a wide range; it can be launched in a folded state, the overall weight is light, the structure is compact, and space is saved ; It can be applied repeatedly, has high efficiency, can be used for a long time in orbit, and has good economic benefits.

Description

technical field [0001] The invention relates to an end effector for active soft capture of space debris, belonging to the field of active removal of space debris. Background technique [0002] As of December 31, 2013, the number of on-orbit debris cataloged by the US Space Monitoring Network has reached 16,906, while the number of tiny debris that cannot be cataloged exceeds 20 billion. The impact speed of space debris on the spacecraft can be as high as 15km / s. Once it collides with the spacecraft, it will damage or even directly destroy the spacecraft in orbit. greatest threat to safe operation. [0003] The United States, Europe, and Japan started research on the active removal of space debris earlier, and have proposed their own debris removal programs, and some key technologies have been demonstrated in orbit. But in general, the current level of development is still far from the in-orbit application, and is still in the stage of breakthrough and mastery of key techno...
