飞机自动防滑刹车系统的控制原理、组成部件和故障排除研究——以B737-700机型为例

The Control Principle,Components and Troubleshooting of the Anti-Skid Braking System of AircraftB737-700

对B737-700机型自动防滑刹车系统的控制原理、组成部件以及常见的故障和排除方法进行论述。总体看,B737一700飞机自动防滑刹车系统可靠性比较高,但传感部分的部件故障偏多,4个机轮刹车组件使用中可能发生的故障主要有过热、卡滞、漏油、振动等。在飞机再次使用前,必须对其机轮刹车组件进行定期检查,且在排除常见的自动防滑刹车系统故障时,应当对波音的手册综合运用并进行交叉验证,同时运用自己的判断力,使故障得到快速、准确的排除。

The paper discusses the control principle,constituent elements of the automatic anti-skid braking system of Aircraft B737-700 and its common faults and elimination method.On the whole,the system is reliable with most failures occurring on its sensing part.The common faults of the braking components of the four airplane wheels are overheating,binding,oil leakage and vibration.Therefore,the braking component must be checked regularly before the plane is used.In eliminating the common faults of the automatic anti-skid braking system,the integrated use of Boeing's manual and cross validation should be conducted to make a fast and accurate judgment.
