论文摘要
机理 - 刚性元件的集合，结合完美的铰链，表现为零能量运动 - 激发了各种机械超材料的设计。我们通过考虑伪机制，弹性耦合元素的集合来显着扩大该设计空间，这些元素表现出非常低的能源成本的运动。我们表明它们的几何设计通常与真实机制不同，因此开辟了一个大型且几乎没有开发的设计空间。我们通过设计具有双态和可三十型能量景观的构建块，进一步扩展了这个空间，通过3D打印来实现这些空间，并展示这些如何形成多稳态超材料的单位单元。
Mechanism - collections of rigid elements coupled by perfect hinges which exhibit a zero-energy motion -- motivate the design of a variety of mechanical metamaterials. We significantly enlarge this design space by considering pseudo-mechanisms, collections of elastically coupled elements that exhibit motions with very low energy costs. We show that their geometric design generally is distinct from those of true mechanisms, thus opening up a large and virtually unexplored design space. We further extend this space by designing building blocks with bistable and tristable energy landscapes, realize these by 3D printing, and show how these form unit cells for multistable metamaterials.
