The invention discloses a deformed wing follow-up loading mechanism based on parallel cable driving, and relates to the field of aerospace equipment. The problems that an existing loading experiment device cannot simulate a severe, complex and variable pneumatic environment, so that the rigidity, stability, bearing capacity and other indexes of a wing structure are difficult to accurately verify, and the performance of a wing is not easy to judge are solved. One end of each rope is fixed on the surfaces of a force loading movable platform assembly and a wing, and the other end of each rope bypasses a series of pulleys on a static platform rope driving module and is connected to a hinge shaft. In the follow-up loading process, a motor drives a lead screw and a hinge shaft to adjust the position and posture of a movable platform in space, so that the spatial direction of a plurality of loading cables connected to a force loading movable platform assembly is changed, and then the tension of a rope connected to the surface of a tested wing is adjusted, so that the tension applied to the wing surface is changed; the variable aerodynamic load of the folding wing in the unfolding process is simulated. The pneumatic load simulation device is used for achieving various pneumatic load simulation effects.
一种基于并联索驱动的变形翼随动加载机构,它涉及航空航天设备领域。本发明解决了现有的加载实验设备存在无法模拟出恶劣、复杂、变化的气动环境,因而难以准确的验证机翼结构的刚度、稳定性和承载能力等指标,不利于判断机翼的性能的问题。本发明中所有绳索一端固定在力加载动平台组件及机翼表面上,另一端绕过静平台绳索驱动模组上的一系列滑轮连接到绞轴上。在随动加载过程中,通过电机驱动丝杠和绞轴调整动平台在空间中的位姿使连接在力加载动平台组件上的若干根加载索的空间指向发生改变,进而调整连接在被测试机翼表面绳索的张力使对翼面施加的拉力改变,以模拟折叠翼在展开过程中受到的变化气动载荷。本发明用于实现多种气动载荷模拟效果。
