The invention discloses a variable-stiffness wing test support device which comprises a vertical cantilever beam mechanism, a horizontal cantilever beam mechanism, a wing support joint and an adjusting pull rod. According to the invention, simulation of vertical and horizontal support stiffness of a wing support part can be realized; by adjusting the length of the cantilever section of the variable stiffness beam, various support rigidities can be simulated, the universality is high, and the test cost is reduced; the joints are hinged, so that decoupling of vertical rigidity and horizontal rigidity can be realized, mutual influence of rigidity in two directions is eliminated, and test precision is improved.

    本发明一种变刚度机翼试验支持装置,包括竖向悬臂梁机构、水平悬臂梁机构、机翼支持接头和调节拉杆。本发明可实现机翼支持部位竖向和水平支持刚度的模拟;通过调整变刚度梁悬臂段的长度,可以模拟多种支持刚度,通用性较强,降低试验成本;各接头采用铰接的形式,可以实现竖向和水平刚度的解耦,消除了两个方向刚度的相互影响,提升试验精度。
