Abstract

The invention discloses an electromagnetic damping buffer foldable attachment leg for small celestial body detection. In order to adapt to small celestial body detection task requirements, equivalentdamping is generated by force control of a motor to realize landing buffering of landing legs; meanwhile, the design of the foldable landing legs is adopted, and a driving motor in folding motion anda motor for buffering and energy absorption are reused, so that the landing legs have a buffering function while being folded, and the problems that the buffering performance of a traditional buffering landing leg mechanism cannot meet the requirement, and the buffering landing design means is single are solved.

Description

technical field [0001] The invention relates to an electromagnetic damping buffer foldable attachment leg for small celestial body detection, which belongs to the field of deep space detection. Background technique [0002] With the development of space exploration technology, the landing detection of small celestial bodies has become another hot spot after the exploration of the moon and Mars. Due to the limitations of weak gravity, short spin period, complex and changeable surface terrain, and unknown surface medium properties, small celestial bodies have extremely adverse effects on the landing of the probe. When the probe lands on its surface, the container rebounds, or lands The rear container floats away. Therefore, the landing legs of small astrophysical probes are required to have excellent cushioning characteristics, which can absorb the landing energy well when the probe lands, so that the residual energy of landing is reduced to a minimum, and it is ensured that ...
