The embodiment of the invention relates to the technical field of aircraft brake control, in particular to an undercarriage folding brake control method capable of inhibiting undercarriage shimmy, and the method comprises the following steps: acquiring a wheel load switch signal, an undercarriage folding switch signal and an aircraft wheel speed signal; judging whether the aircraft is in a take-off state at present according to the wheel load switch signal, the undercarriage take-up switch signal and the aircraft wheel speed signal; if the aircraft is in the take-off state at present, undercarriage take-up brake operation is executed, and undercarriage take-up brake pressure is output to aircraft wheels step by step according to a preset brake pressure output strategy; and when it is detected that the time for executing the landing gear brake retracting operation reaches the first preset time, static brake pressure is output to the aircraft wheels, and the landing gear brake retracting operation is ended. According to the method, shimmy of the undercarriage in the process that the undercarriage is retracted into the brake is well restrained, the use reliability of an aircraft wheel brake system is improved, and then the use safety of an aircraft is effectively improved.

    本申请的实施例涉及飞机刹车控制技术领域,特别涉及一种可抑制起落架摆振的起落架收上刹车控制方法,该方法包括:获取轮载开关信号、起落架收上开关信号和机轮速度信号;根据轮载开关信号、起落架收上开关信号和机轮速度信号,判断飞机当前是否处于起飞状态;若飞机当前处于起飞状态,则执行起落架收上刹车操作,按照预设的刹车压力输出策略向飞机机轮逐步输出起落架收上刹车压力;当检测到执行起落架收上刹车操作的时间达到第一预设时间后,向飞机机轮输出静态刹车压力,结束起落架收上刹车操作。该方法很好地抑制了起落架收上刹车过程中起落架的摆振,提升了飞机机轮刹车系统的使用可靠性,进而有效提升了飞机的使用安全。
