形状可変性タイヤホイール設計に向けたAuxeticリング構造体のフレキシブル空圧幾何変形

The fabrication of shape-changing structures has been positioned as a core seed for future technologies that will contribute to the development of aeronautics and minimally invasive surgery. In particular, the use of soft gels and elastomers can be expected to enable rapid and diverse shape deformation. Furthermore, it is possible to dynamically control the deformation from a two-dimensional sheet to a three-dimensional structure by introducing air. It has been reported that, for example, a camouflage structure by pneumatic control inspired by the skin deformation of an octopus, and a Gaussian surface that can be freely deformed by devising a flow pattern. In this study, we fabricated a structure with wheel-shaped auxetic ring structural deformation of the rotation mechanism using a 3D printer and investigated the mechanical 3D deformation.
