The invention discloses a bionic variable stiffness folding and unfolding structure based on locust wings, and belongs to the field of spacecrafts. Wherein the base body is used for simulating a body trunk part of a locust; the two folding and unfolding array surfaces are used for simulating locust wings and are symmetrically arranged on the left and right sides of the base body. The two folding and unfolding array surfaces are composed of a plurality of frameworks, the front ends of the plurality of frameworks can slide along sliding rails on the two sides of the base body, so that the plurality of frameworks are unfolded and folded in a sector unfolding mode, and the certainty and orderliness of movement among the plurality of frameworks are guaranteed. The adjacent frameworks are connected through a shear fork linkage unfolding device, and synchronism of movement between the frameworks is achieved. According to the invention, the super-large unfolding and folding ratio design of the spacecraft structure can be realized, and meanwhile, the method has a simple and reliable unfolding and folding form and strong and stable anti-interference performance, and ensures the safety and reliability of in-orbit operation of the spacecraft.
本发明公开一种基于蝗虫翅翼的仿生变刚度折叠展开结构,属于空间飞行器领域,由基体与折展阵面组成。其中,基体用于模拟蝗虫的身体主干部分;两个折展阵面用于模拟蝗虫翅膀,左右对称布置安装于基体左右两侧。两个折展阵面由多根骨架构成,多根骨架前端可沿基体两侧滑轨滑动,使多根骨架以扇面展开方式进行展收,实现多根骨架保证骨架间运动的确定性和有序性。上述相邻骨架间通过剪叉联动展开装置相连,实现个骨架间运动的同步性。本发明可实现航天器结构超大展收比设计,同时具备简单可靠展收形式、强稳定的抗干扰性能,确保航天器在轨运行的安全可靠。
