The invention discloses a flexible wing load loading method, and belongs to the technical field of aircraft load tests. According to the loading method, a load loading mechanism is installed on a multi-degree-of-freedom motion platform, the multi-degree-of-freedom motion platform comprises four displacement sensors arranged on a fixed bottom plate and used for measuring the vertical displacement of a tension and compression pad for loading relative to the fixed bottom plate, and the distances between the four displacement sensors and the central axis of the fixed bottom plate are the same; the connecting line between the first displacement sensor and the second displacement sensor is perpendicular to the connecting line between the third displacement sensor and the fourth displacement sensor. The controller is used for controlling each motion driving mechanism according to the measured values of the four displacement sensors and the displacement of the loading driving mechanism during loading, so that the loading direction of the loading driving mechanism is always vertical to the lower surface of the wing. By continuously correcting the load direction in the loading process, the accuracy of each stage of load in the loading process of the flexible wing is ensured, so that the magnitude of the loaded load is accurately controlled.
本发明公开了一种柔性机翼载荷加载方法,属于飞行器载荷试验技术领域。该加载方法将载荷加载机构安装在多自由度运动平台上,多自由度运动平台包括设置在固定底板上的四个位移传感器,用于测量加载用拉压垫相对于固定底板的垂直位移,四个位移传感器与固定底板的中心轴线距离相同,且第一和第二位移传感器之间的连线与第三和第四位移传感器之间的连线垂直;控制器在载荷加载时根据四个位移传感器的测量值和加载驱动机构的位移量,控制各运动驱动机构,以使加载驱动机构的载荷加载方向始终垂直于机翼下表面。本发明通过在加载过程中不断校正载荷方向,保证柔性机翼加载过程中每一级载荷的准确性,从而实现对加载载荷大小进行精确控制。
