The invention relates to the technical field of aircraft shimmy damping, and provides an undercarriage shimmy damper and an aircraft, the undercarriage shimmy damper comprises a first cylinder barrel, a piston column, a rocker arm and an oil pressure adjusting mechanism, the piston column is slidably arranged in the first cylinder barrel, a damping hole is formed in the piston column, and the two axial ends of the piston column are communicated through the damping hole; the oil pressure adjusting mechanism is additionally arranged, the oil pressure adjusting mechanism can be switched between the first state and the second state, when the temperature of oil in the first cylinder barrel rises and the pressure of the oil in the first cylinder barrel is increased, the oil enables the oil pressure adjusting mechanism to be switched to the first state, and the damping hole is formed in the second cylinder barrel. The oil liquid pressure adjusting mechanism provides an oil liquid buffering space for the oil liquid, pressure relief and cooling can be conducted on the oil liquid in the first cylinder barrel, and the shimmy damping effect of the shimmy damper is guaranteed.

    本发明涉及飞机减摆技术领域,提供一种起落架减摆器及飞机,包括第一缸筒、活塞柱、摇臂和油液压力调节机构,活塞柱可滑动地设于第一缸筒内,活塞柱内设有阻尼孔,活塞柱的轴向两端通过阻尼孔相连通,油液压力调节机构与阻尼孔相连通,通过增设油液压力调节机构,油液压力调节机构能够在第一状态与第二状态之间切换,当第一缸筒内油液温度升高,压力增大时,油液使油液压力调节机构切换至第一状态,油液压力调节机构为油液提供油液缓冲空间,可以对第一缸筒内的油液进行泄压和降温,保证了减摆器的减摆效果。
