Combined docking cone

Abstract

The invention provides a combined abutting-joint cone which comprises abutting-joint discs. The abutting-joint discs are provided with abutting-joint holes. The combined abutting-joint cone further comprises a plurality of abutting-joint plates, the first ends of the plurality of abutting-joint plates are evenly and fixedly arranged on the abutting-joint discs along the peripheral directions of the abutting-joint holes, and the second ends of the plurality of abutting-joint plates form a cone shape towards the center of the abutting-joint discs in an inclined mode. According to the combined abutting-joint cone, the abutting-joint discs are adopted, the plurality of abutting-joint plates are arranged on the abutting-joint discs to form the cone shape, and therefore in the docking process of spacecraft, relaying on the self-structural flexibility of the abutting-joint plates, when a abutting-joint rod collides with the abutting-joint plates, the abutting-joint plates can generate great deformation to prolong contacting time, a colliding force peak value is reduced, a large amount of shocking kinetic energy is absorbed and dissipated, and therefore the buffering problem is effectively solved in a small and medium size spacecraft docking process.

Description

technical field [0001] The invention relates to the field of docking devices for small and medium-sized spacecraft, in particular to a combined docking cone. Background technique [0002] To realize space autonomous rendezvous and docking technology, the collision problem of the docking mechanisms of the two spacecraft must first be considered. In order to avoid unnecessary damage and deformation of the spacecraft during the collision process, and even cause danger to the spacecraft, to ensure the safety of the two docked spacecraft and to achieve reliable docking, a buffer damping system must be installed on the docking mechanism. [0003] The monograph "Spacecraft Autonomous Rendezvous and Docking Technology" (written by FehseW, translated by Li Dongxu and Li Zhi, National University of Defense Technology Press, 2009) describes a buffer damping system for a cone-rod docking mechanism. The transmission and buffering process are unified in a set of buffering and damping sys...
