Abstract

The invention discloses a weak impact type butting system for androgynous stiffness damping closed loop feedback control. Butting mechanisms of two spacecrafts are contacted to generate mutual action under specified initial conditions, the butt ring of the butting mechanism of a driving spacecraft generates position and posture deviation, and the relative deviations of the two butting mechanisms are adapted; the driving butting mechanism measures the displacement of six linear driving mechanisms which are connected with the butt ring and calculates the motion speed and posture of the butt ring; buffer damping data required by the butt ring of the driving butting mechanism is determined according to a preset control rule; and reactive force is generated through motors arranged on the six linear driving devices, and the linear driving devices are directly driven to capture and buffer the butting process. The collision load can be controlled in a narrow range in the butting process, weak impact butt is realized, butt and separation of different butting quality targets can be realized by changing the control rule, and butting between the spacecrafts and the existing manned spacecraft can be realized.

Description

technical field [0001] The invention relates to an aerospace vehicle device, and relates to a space docking device, in particular, the invention relates to a stiffness-damping closed-loop feedback control and a weak impact docking system for two spacecraft. Background technique [0002] The space docking system can make two spacecraft combine in space orbit and connect structurally as a whole. It is widely used in the fields of on-orbit assembly, recovery, supply, maintenance and space rescue of large facilities such as space stations, space laboratories, space communication and remote sensing platforms. For example: Shenzhou-9 and Tiangong-1 realize the docking between the two through the docking system, and the astronauts of Shenzhou-9 enter the experimental cabin of Tiangong-1 through the docking channel. [0003] Most docking systems have a mechanical structure that includes locks, shackles, and other mechanisms. Generally, there are two ways to realize the connection ...
