机械超材料的伪机构和多稳态单元设计
Design of pseudo-mechanisms and multistable units for mechanical metamaterials
摘要：
机械--由完美的铰链连接的刚性元件的集合，这些铰链表现出零能量运动--激发了各种机械超材料的设计。我们显着扩大了这个设计空间，考虑伪机构，集合弹性耦合元件，表现出非常低的能量成本的运动。我们表明，他们的几何设计一般是不同于那些真正的机制，从而开辟了一个大的，几乎未开发的设计空间。我们通过设计具有双稳态和三稳态能量景观的构建块来进一步扩展这个空间，通过3D打印实现这些，并展示这些如何形成多稳态超材料的单位单元。
英文摘要：
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.
