The invention discloses a recoverable landing buffer mechanism and a recoverable landing buffer method for a lunar probe. The buffer mechanism is located at the bottom of a landing leg of the lunar probe and is composed of an outer cylinder, a push rod, a foot pad, a net-shaped buffer element, a powder damping material, a viscoelastic damping element and a force transmission element. In the landing process of the detector, the foot pad and the push rod drive the force transmission element to move upwards, the net-shaped buffering element is compressed, meanwhile, the elastic damping element is sheared and stretched, a large amount of impact energy is consumed, and stable landing of the detector is achieved; and after the detector takes off again, the deformation of the net-shaped buffer element and the viscoelastic damping element can be slowly released, and the deformation of the buffer mechanism can be completely recovered. The buffering mechanism has the advantages of being high in damping, recoverable, high in stability and the like, has an excellent single-time buffering effect under the condition that no external energy is needed, and can meet the requirement for multiple times of buffering when the detector takes off and lands. Meanwhile, the mechanism can stably and efficiently work for a long time in the extreme environment of the moon.
本发明公开了一种月球探测器可恢复着陆缓冲机构及缓冲方法。缓冲机构位于月球探测器着陆腿底部,由外筒、推杆、足垫、网状缓冲元件、粉末阻尼材料、粘弹性阻尼元件及传力元件组成。在探测器着陆过程中,足垫和推杆带动传力元件向上运动,压缩网状缓冲元件,同时剪切和拉伸弹性阻尼元件,大量消耗冲击能量,使探测器实现平稳着陆;当探测器再次起飞后,网状缓冲元件及粘弹性阻尼元件的变形会缓慢释放,缓冲机构的变形可完全恢复。该缓冲机构具有高阻尼、可恢复和高稳定性等特点,在无需外部能源的情况下,既具有优异的单次缓冲效果,也可满足探测器起飞和着陆时的多次缓冲要求。同时,该机构还可在月球极端环境下长期稳定且高效工作。
