摘　　要：随着工业自动化以及电力电子技术的发展,伺服电动缸凭借其结构简单、控制精度高等优点,已开始在飞机结构强度试验中逐步应用推广。在某民机襟翼疲劳试验中引人了电动缸作为执行机构,控制随动框架的运动,由于襟翼翼面与试验件存在因偏转过程中运动不同步而引发的试验件拉扯损伤风险,本文提出了襟翼与随动框架的同步运动控制技术。通过在测试并成功应用在某飞机襟翼疲劳试验中,襟翼与随动加载框架的同步运动控制精度高、可靠性好,满足某型飞机襟翼疲劳试验要求。With the development of industrial automation and power electronics technology.servo-electric cylinders have begun to be gradually applied and promoted in aircraft structural strength tests due to their advantages of simple structure and high control accuracy.In a civil aircraft flap fatigue test.an electric cylinder is introduced as actuator to control the motion of the servo frame.Since the flap surface and test part have the risk of pulling damage caused by the movement of the test part during the deflection process,the synchronous motion control technology of the flap and the flap and servo frame id proposed in this paper.Through the test and successful application in the fatigue test of an aircrafts flap,the synchronous motion control technology of the flap and the follow-up loading frame has high control accuracy and good reliability,which meets the fatigue test requirements of a certain type of aircraft.
