摘　　要：载荷校准试验是应变法飞行载荷测量工作中必要的环节,其试验结果决定着飞行载荷测量成败。通常载荷校准试验是在飞机上实施的,具有较大的风险,为此在正式试验前要进行加载设备调试、工况演示,进而实现工况优化,降低试验风险。针对调试试验提出了一种可变刚度的载荷校准试验调试台架,通过对空气弹簧调节台架整体刚度,实现机翼受载后的变形模拟。试验结果表明,该调试台架的功能和承载能力能够满足调试试验的需求,能实现大展弦比机翼的大变形模拟。The load calibration test is an important part of the flight load measurement, and the test results determine the success or failure of the flight load measurement. In order to reduce the risk of the test and improve the accuracy of the test, debugging of loading equipment and demonstration of working conditions should be carried out before the formal test. A vari- able stiffness load calibration test bench is put forward, which is used to simulate large deformation of large aspect ratio wing after loading. The test results show that the function and caDacitv of the device can meet the test requirement.
