Docking mechanism driving and buffering system with controllable damping

Abstract

The invention discloses a docking mechanism driving and buffering system with the controllable damping. The docking mechanism driving and buffering system with the controllable damping is an androgynous peripheral docking mechanism and comprises multiple groups of screw rod connection assemblies, a differential motion assembly, a main driving assembly, and multiple controllable dampers, wherein the screw rod connection assemblies used as upper support point parts are connected onto a docking frame; the docking frame is arranged on a docking ring; screw rod installation seats are lower supportpoint parts and are combined into the differential motion assembly; the differential motion assembly is connected with the main driving assembly; the controllable dampers are arranged between the screw rod installation seats, and are arranged to be electromagnetic dampers capable of being controlled to switch on and switch off a damping function during the docking buffering process. The characteristic of the softness of the system is ensured during the docking acquiring process; once if the docking mechanism acquires, the controllable dampers are switched on, so that the damping of the whole driving and buffering system is hardened, the buffering energy dissipation is greatly improved, the wide-range docking adaptability of the docking mechanism is improved, and meanwhile, the parameters of an original system can be ensured to be slightly changed or 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
