电传飞控系统中处于故障状态的电子部件产生虚假正弦信号引起的振荡信号通过伺服控制线路传至舵面从而导致舵面振荡故障,舵面振荡会影响对飞机飞行轨迹的控制,严重的振荡故障可能导致飞机丧失结构的完整性从而造成更大的灾难,本文介绍了采用电传飞控系统的某型号对飞机振荡检测的一种实现形式,及振荡监控功能所完成的符合性验证工作。
Electronic components in fly-by telemetry flight control system produce false sinusoidal signal caused by the oscillation signal is transmitted to the rudder through the servo control circuit resulting in rudder oscillation failure, the rudder oscillation will affect the control of the flight path of the aircraft, severe oscillation Failure can cause the aircraft to lose its structural integrity and cause more disasters. This paper presents an implementation of aircraft vibration detection using a model of a fly-by-wire flight control system and the compliance verification performed by the vibration monitoring function.
