The invention relates to a shimmy damping device, an undercarriage and an aircraft. The shimmy damping device comprises a movable module, a sleeve, a friction piece and an adjusting module, and the movable module is rotatably arranged on a first supporting piece; the sleeve is rotatably arranged on the second supporting piece, the sleeve is arranged outside the movable module in a sleeving mode, and the movable module can reciprocate in the axis direction of the sleeve; the friction piece is arranged on the outer wall of the movable module and is in sliding fit with the inner wall of the sleeve; the adjusting module is arranged on the movable module and used for adjusting the friction force of the friction piece acting on the inner wall of the sleeve. Compared with the prior art, the shimmy damping device can prevent the rolling wheel from shimmy through friction damping generated by the friction piece and the inner wall of the sleeve, the overall weight and size of the structure are small, and therefore the flight safety of the small and light aircraft is guaranteed.
本申请涉及一种减摆装置、起落架及飞行器,减摆装置包括活动模块、套筒、摩擦件以及调节模块,活动模块可转动地设于第一支撑件;套筒可转动地设于第二支撑件,套筒套设于活动模块外,活动模块能够沿套筒的轴线方向往复移动;摩擦件设于活动模块的外壁并与套筒的内壁滑动配合;调节模块设于活动模块,调节模块用于调节摩擦件作用于套筒的内壁的摩擦力的大小。与传统技术相比,上述的减摆装置能够通过摩擦件与套筒的内壁所产生的摩擦阻尼来阻止滚轮发生摆振,结构整体的重量和体积小,从而确保小轻型飞行器的飞行安全。
