Abstract

Inflatable pads, such as those used as mattresses or protective equipment, are structures made of two planar membranes sealed according to periodic patterns, typically parallel lines or dots. In this work, we propose to treat these inflatables as metamaterials.

By considering novel sealing patterns with 6-fold symmetry, we are able to generate a family of inflatable materials whose macroscale contraction is isotropic and can be modulated by controlling the parameters of the seals. We leverage this property of our inflatable materials family to propose a simple and effective algorithm based on conformal mapping that allows us to design the layout of inflatable structures that can be fabricated flat and whose inflated shapes approximate those of given target freeform surfaces.

材料:用于自由曲面设计的各向同性充气超材料
充气垫,比如那些用作床垫或防护设备的,是由两个平面膜组成的结构,按照周期性的模式密封,通常是平行线或点。在这项工作中,我们建议将这些可膨胀物视为超材料。通过考虑具有6重对称的新型密封模式,我们能够生成一系列可膨胀材料,其宏观尺度收缩是各向同性的,并且可以通过控制密封参数来调节。我们利用充气材料家族的这一特性,提出了一种基于保角映射的简单有效的算法,该算法允许我们设计可平面制造的充气结构的布局,其充气形状近似于给定目标自由曲面的形状。
