The invention discloses a fault detection method for an airplane wheel brake system. The method comprises the steps: based on an existing brake controller, a stop valve, a servo valve and a sensor of the airplane wheel brake system, judging whether a fault condition is satisfied or not through detected brake pressure, and determining whether the airplane wheel brake system fails or not, thereby achieving the purpose of fault detection of the airplane wheel brake system. Therefore, the faulty equipment is accurately located, the workload of maintenance personnel is reduced, the fault isolation rate of the airplane brake system is improved from 63% to 78%, the fault can be accurately positioned to the brake control unit, the stop valve and the servo valve, and the implementation difficulty and cost of fault detection of the airplane wheel brake system are reduced.

    一种飞机机轮刹车系统的故障检测方法,基于机轮刹车系统现有的刹车控制器、切断阀、伺服阀和传感器,分别通过检测的刹车压力判断是否满足故障条件,以确定所述机轮刹车系统是否失效,从而实现了对机轮刹车系统的故障检测的目的,并且精确定位到故障设备,减轻了维护人员的工作负担,将飞机刹车系统的故障隔离率由63%提高到78%,能够将故障精确定位到刹车控制单元、切断阀、伺服阀,降低了对机轮刹车系统的故障检测的实施难度和成本。
