Abstract

The invention relates to the field of space robot engineering research, in particular to a space soft docking device based on a gyroscope structure, which comprises a gyroscope structure assembly and a sliding structure assembly. The gyroscope structure assembly comprises a gyroscope mechanism, a rotating flexible part, an encoder and the like. The sliding structure assembly mainly comprises a sliding mechanism, a linear flexible part, a linear displacement sensor and the like. According to the space soft docking device, the space six-dimensional docking collision impulse can be transmitted through the gyro mechanism and the sliding mechanism, the collision impulse is buffered through the torsional spring mechanism and the spring mechanism, and finally damping output of the magneto-rheological damper is planned through the encoder and the linear displacement sensor to achieve stabilization of internal vibration of the space soft docking device. Therefore, the soft docking operation of space on-orbit capture is realized.

Description

technical field [0001] The invention relates to the field of space robot engineering research, in particular to a space soft docking device based on a gyroscope structure. Background technique [0002] Target capture is an important part of space on-orbit service, but the docking collision during capture can easily cause the capture mechanism to become unstable. It is of great significance to achieve the space on-orbit capture task to realize the docking soft contact when the space on-orbit target is captured. [0003] At present, there have been a lot of practice in the research of space soft capture technology based on docking mechanism in the world, mainly including cone-rod docking system, flying net technology, electromagnetic docking and so on. The characteristics of the above docking mechanism are that the flexible rope is used as the main actuator or the capture subsystem is designed by the relevant mechanism at the end effector; the constraints require that the rel...
