Abstract

The invention discloses an attached device of a deep-space weak-gravitation celestial body and a method for constructing the attached device. The attached device comprises an upper frame, a lower frame, truss girders and a plurality of leg structures; the upper frame is connected with the lower frame by the truss girders, each leg structure comprises a main leg and auxiliary legs, a first end of each main leg is connected onto the upper frame, a first end of each auxiliary leg is connected onto the lower frame, and a second end of each main leg and second ends of the corresponding auxiliary legs are connected with a foot cushion by connecting hinges; and aluminum honeycomb pressure-fed buffer material structures are arranged inside the main legs and the auxiliary legs. The attached device and the method have the technical advantages of simple structure, good stability, low pressure-fed threshold, difficulty in rebounding, high bearing capacity in weak-gravitation environments, and the like.

Description

Technical field [0001] The invention relates to the technical field of landing of deep-space celestial bodies, in particular to a deep-space weak gravitational celestial body attachment device and a construction method thereof. Background technique [0002] In my country's future asteroid attachment detection missions, the probe will attach to near-Earth asteroids for scientific exploration. Near-Earth asteroids have the characteristics of small mass and irregular shape, and are typical weak gravitational celestial bodies. The escape speed of weak gravitational bodies is small, and the attachment device is required to quickly absorb the impact energy and firmly attach to the asteroid. The traditional lunar and Mars landing devices will not be suitable for the attachment of weak gravitational celestial bodies. To this end, the design of attachment devices for deep-space weak-gravity celestial bodies is carried out. Summary of the invention [0003] Aiming at the above-mentioned s...
