摘　　要：操纵面极限环振荡现象不仅广泛存在于飞机使用阶段,而且经常发生在地面维修阶段。针对此问题,在梳理操纵面多种极限环振荡原因的基础上,建立极限环振荡模型,利用该模型对某型飞机维修阶段出现的操纵面极限环振荡现象进行原因分析、试验验证及抑制方法制定。研究结果表明,无法有效衰减及滤除与飞机固有频率接近的平尾扰动信号是引发平尾异常振荡的根本原因,可以通过调整飞机支撑形式、处理俯仰角速率传感器感知信号等方法进行抑制。The control surface limit cycle oscillation phenomenon not only widely exists in the aircraft use stage,but also often occurs in the ground maintenance stage.In order to solve this problem,a limit cycle oscillation model is established based on the analysis of various causes of limit cycle oscillation on the control surface,and the cause analysis,test verification and suppression methods are made by using the model.The research results show that the failure to effectively attenuate and flter the horizontal tail disturbance signal close to the natural frequency of the aircraft is the fundamental cause of the horizontal tail abnormal oscillation,which can be suppressed by adjusting the support form of the aircraft and processing the sensing signal of the pitch rate sensor.
