摘　　要：针对某运输类飞机副翼的结构及受力特点,确定了应变片粘贴位置及组桥方式,设计了标定加载试验,运用多元回归方法建立了载荷标定方程,并进行了试验验证,确保后续飞机副翼载荷飞行实测结果的准确性,为副翼结构的定寿延寿及可靠性设计提供了重要依据。According to the mechanical structure and the load characteristics of the aileron of a transport aircraft,the arrangement of the measuring strain gages and the type of the strain gage bridges are determined.A ground calibration test device for aileron structure load test is designed,and the load calibration equation is established by using multiple regression method.The load calibration equation results are verified by the test to ensure the accuracy of the aircraft aileron measured load,which provides an important reference for estimating and enhancing the fatigue life and conducting the reliability-based design.
