The invention discloses a negative Poisson's ratio metamaterial structural member which is of a double-layer concave hexagonal structure and serves as a supporting piece of a deformable wing. The metamaterial structural members are arranged in a single-row array mode in the wing chord direction of the wing. The metamaterial structural member comprises 6 straight rods and 16 connecting rods, every two connecting rods are parallel to each other and are arranged between every two straight rods in the same inclined direction, and every two straight rods are spatially parallel to each other; the metamaterial structural members designed by the invention are connected through a linear array in a three-dimensional space to form a supporting structure. The deformation direction of the metamaterial structural member is more stable, and Poisson's ratio adjustability within a certain range is achieved.

    本发明公开了一种作为可变形机翼的支撑件的双层内凹六边形结构的负泊松比超材料结构件,该超材料结构件沿机翼翼弦方向单排阵列排布;超材料结构件包括有6根直杆和16根连杆,所述连杆为两两平行且保持同一倾斜方向设置在两两直杆之间,两两直杆为空间平行布置;本发明设计的超材料结构件在三维空间内通过线性阵列连接形成支撑结构。本发明的超材料结构件的变形方向更稳定,具有一定范围的泊松比可调节性。
