The invention relates to a control method for a magneto-rheological shimmy damper of an aircraft landing gear. The control method comprises the steps that the aircraft height, the aircraft flight speed, the aircraft flight deceleration and the aircraft descent speed are obtained; when the aircraft height is lower than a first height threshold value and higher than a second height threshold value,the initial working current of a coil of the magneto-rheological shimmy damper is obtained according to the aircraft flight speed, the aircraft flight deceleration and the aircraft descent speed; whenthe height of the aircraft is lower than a second height threshold value, acquiring an aircraft taxiing speed, an aircraft wheel swing angle, an aircraft wheel swing angle speed and an aircraft wheelswing angle acceleration; and the initial working current is adjusted according to the airplane taxiing speed, the airplane wheel swing angle, the airplane wheel swing angle speed and the airplane wheel swing angle acceleration, and a final working current value is obtained. Firstly, the control process of the control method is simple and free of cumbersome, the control reliability is further improved, the working current of the magneto-rheological shimmy damper coil can be accurately controlled, and the damping of the magneto-rheological shimmy damper can meet the requirement.

    本发明涉及一种用于飞机起落架磁流变减摆器的控制方法,获取飞机高度、飞机飞行速度、飞机飞行减速度以及飞机下降速度;当飞机高度低于第一高度阈值且高于第二高度阈值时,根据飞机飞行速度、飞机飞行减速度以及飞机下降速度获取磁流变减摆器的线圈的初始工作电流;当飞机高度低于第二高度阈值时,获取飞机滑行速度、机轮摆角、机轮摆动角速度和机轮摆动角加速度;根据飞机滑行速度、机轮摆角、机轮摆动角速度和机轮摆动角加速度对初始工作电流进行调节,得到工作电流最终值。首先,该控制方法的控制过程比较简单,毫无繁琐,进而提升控制可靠性,而且,能够精确控制磁流变减摆器线圈的工作电流,使磁流变减摆器的阻尼满足要求。
