受最近屈曲诱导可重构结构成功的启发，提出了一类利用弯曲梁在旋转输入下屈曲的新型可展开系统。首先，采用实验和数值相结合的方法研究了梁的几何参数对其非线性响应的影响。结果表明，通过组合弯曲梁可以实现多种可展开的结构。最后，提出的原则被用于建造可展开的家具，如桌子和灯罩，这些家具扁平/紧凑，便于运输和存储，需要简单或不需要组装，并且可以通过应用简单的旋转输入来扩展。
Inspired by the recent success of buckling-induced reconfigurable structures, a new class of deployable systems that harness buckling of curved beams upon a rotational input is proposed. First, experimental and numerical methods are combined to investigate the influence of the beam's geometric parameters on its non-linear response. Then, it is shown that a wide range of deployable architectures can be realized by combining curved beams. Finally, the proposed principles are used to build deployable furniture such as tables and lamp shades that are flat/compact for transportation and storage, require simple or no assembly, and can be expanded by applying a simple rotational input.
