Abstract Reconfigurable surfaces are useful in many applications. This paper proposes a type of reconfigurable surfaces that consist of rigid elements (tiles) connected by novel compliant joints. Depending on the actuation, these novel connecting joints can either operate as torsional hinges, which create isometric transformation (like origami folding) between connected tiles, or bistable translational springs, which accommodate metric-changing transformation between connected tiles. A specific example of a reconfigurable surface with square tile shape that can morph into flat, cylindrical (in two different directions), and spherical configurations with simple actuation is given.

采用线性旋转和双稳态平移 (LRBT) 关节的可重构表面

摘要 可重构曲面在许多应用中都很有用。本文提出了一种可重构表面,它由通过新型柔性接头连接的刚性元件(瓷砖)组成。根据驱动的不同,这些新颖的连接接头既可以作为扭转铰链,在连接的瓷砖之间产生等距变换(如折纸折叠),也可以作为双稳态平移弹簧,适应连接的瓷砖之间的公制变化变换。给出了一个具有方形瓷砖形状的可重构表面的具体示例,该表面可以通过简单的驱动变形为平面、圆柱形(在两个不同的方向)和球形配置。
