A damping controllable transmission buffer system for docking mechanism

Abstract

The invention discloses a damping-controllable butt joint mechanism transmission buffer system, which is a heterogeneous and isomorphic peripheral joint joint mechanism, including multiple sets of screw connection combinations, differential combinations, and main drive combinations, and the screw connection combination as an upper fulcrum component Connected to the docking frame, the docking frame is set on the docking ring; the screw mounting seat is the lower fulcrum part, multiple screw mounting seats are incorporated into the differential combination, and the differential combination is connected to the main drive combination; it also includes multiple controllable The damper, the controllable damper is arranged between the lead screw mounting seat; the controllable damper is set as an electromagnetic damper which can start and stop the damping function under control during the docking buffering process. The invention guarantees the soft characteristics of the system during the docking capture process. Once the docking mechanism is captured, the controllable damper is switched on, making the damping of the entire transmission buffer system hard, greatly improving the buffering energy consumption capacity, and improving the large-scale docking of the docking mechanism. Adaptability, while ensuring that the original system parameters change little or remain unchanged.

Description

technical field [0001] The invention relates to a space docking device, in particular to a transmission buffer system of a docking mechanism with controllable damping. Background technique [0002] The space docking mechanism (also known as the docking system) can combine two spacecraft on the space orbit and connect them structurally as a whole. It is widely used in space stations, space laboratories, space platforms and other large aircraft, cabins and facilities. In the fields of on-orbit assembly, recovery, supply, maintenance, and space rescue, for example: Shenzhou 8, Shenzhou 9, Shenzhou 10 manned spacecraft and Tiangong 1 target aircraft realize the docking between the two; Shenzhou 10 The No.1 manned spacecraft, the Tianzhou-1 cargo spacecraft and the Tiangong-2 space laboratory realize the docking of the two through the docking system; the astronauts enter the experimental cabins of Tiangong-1 and Tiangong-2 through the docking channel to carry out space exploratio...

AI Technical Summary

Problems solved by technology

When the docking mass is greatly increased to the order of 100 to 200 tons, the energy dissipation capacity of the buffer system of the original docking mechanism will not meet the docking requirements. If the spring damping is improved for the redesign, the capture performance will deteriorate, and the structural Layout constraints lead to a new design of the structural layout
