摘　　要：随着工业自动化及电子技术的发展,伺服电动缸凭借其结构简单、控制精度高等优点,在飞机结构强度试验中逐步得到推广应用。本文在某民机襟翼疲劳试验中,引入电动缸进行随动框架位置控制。为保证力控加载点加载力线的准确性及偏转过程中试验件不被拉扯挤压而损伤,引入了襟翼与随动加载框架的同步运动控制技术。某飞机襟翼疲劳试验测试结果表明,襟翼与随动加载框架的同步运动控制技术控制精度高、可靠性好,满足襟翼疲劳试验要求。With the development of industrial automation and electronic technology,servo-electric cylinder has been gradually popularized and applied in aircraft structural strength tests due to its advantages of simple structure and high control precision.In the fatigue test of a certain type of civil aircraft flap,an electric cylinder is introduced for position control of the follow-up frame.In order to ensure the accuracy of the loading force line of the force-controlled loading point and the test piece is not damaged by pulling and extrusion during the deflection process,the synchronous motion control technology of the flap and the follow-up loading frame is introduced.The fatigue test results of an aircraft flap show that 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.
