The invention provides a cat-shaped moon lander based on a variable-stiffness buffer and a landing method thereof. The lander comprises a lander body, a thighbone cat-leg-imitating structure, the variable-stiffness buffer, a tibia cat-leg-imitating structure, a metatarsal bone cat-leg-imitating structure, a buffer spring, a cat-leg-imitating pad, a shoulder blade cat-leg-imitating structure, a humerus cat-leg-imitating structure and a radius cat-leg-imitating structure. When the cat-foot-imitating pad, the metatarsal-bone cat-leg-imitating structure and the radius cat-leg-imitating structure touch the ground, all the structures drive the variable-rigidity buffer to work, and buffering and speed reduction of the lander are achieved through pulling/pressing movement of the variable-rigidity buffer. Meanwhile, in the landing process, the buffering force and the overall attitude of the lander are controlled by adjusting the rigidity of the variable-rigidity buffer, and finally safe and stable landing of the lander is achieved. The invention can be widely applied to various spaceflight landers, and has the advantages of good buffer effect, wide landing range, controllable landing attitude and the like.
本发明提供了一种基于变刚度缓冲器的仿猫构型月球着陆器及其着陆方法,着陆器包含着陆器机体、股骨仿猫腿结构、变刚度缓冲器、胫骨仿猫腿结构、跖骨仿猫腿结构、缓冲弹簧、仿猫足垫、肩胛骨仿猫腿结构、肱骨仿猫腿结构、桡骨仿猫腿结构。当仿猫足垫、跖骨仿猫腿结构和桡骨仿猫腿结构触地后,各结构带动变刚度缓冲器工作,通过变刚度缓冲器拉/压运动,实现着陆器缓冲减速。同时,在着陆过程中,通过对变刚度缓冲器进行刚度调整,完成着陆器缓冲力及整体姿态控制,最终实现着陆器安全稳定着陆。本发明可广泛应用于各类航天着陆器,具有缓冲效果好、着陆范围广、着陆姿态可控等优点。
