Problems solved by technology

The ground rope hoisting system usually needs to avoid system instability or even accidents due to excessive swing angle of the rope. The swing angle detection is fed back to the actuator and the necessary control strategy is adopted to suppress the swing of the rope within a certain range until it is stable. This type of mechanism The method of suppressing swing by changing the displacement and rotary motion of the suspension point of the rope cannot control the vibration in the direction of the rope

Description

technical field [0001] The invention relates to a tether retractable device, in particular to a tether retractable device with controllable tension and retractable length and measurable line attitude angle. Background technique [0002] On-Orbit Servicing (OOS) is a very active frontier issue in the aerospace field. Many space structures adopt the tether structure, and the control of space rope retraction has an important impact on the stability of satellite space attitude, and the retraction of the tether is a key technology. The application of ropes in space has achieved fruitful results through years of experimental and theoretical research. Compared with rigid bodies or flexible bodies, ropes have unique mechanical properties such as force directionality, greater toughness, time-varying nonlinearity of stress-strain relationship, and light weight. In order to meet the requirements of tether length, speed, and tension control, Space tether retractable device design has ...
