基于泰森多边形的仿生多孔结构设计方法

Biomimetic Porous Structure Design Method Based on Voronoi Diagram

本研究采用泰森多边形原理设计了仿生多孔结构,利用参数化方法获得了联通多孔模型,实现了与骨缺损形状匹配的自由几何构造。与此同时,围绕孔隙率、孔径、孔棱直径、比表面积四个参数开展了设计参数与几何参数之间的关联探究,为实际工程应用提供了一定的理论依据。基于该方法生成的不规则多孔模型可通过增材制造、立体成像等技术进行3D打印。

In this study, the Voronoi Diagram principle was used to design a bionic porous structure, and a parametric method was used to obtain a linked porous model to achieve a free geometric configura-tion matching the shape of the bone defect. At the same time, the correlation between the design parameters and geometric parameters was explored around four parameters: porosity, pore diam-eter, pore prism diameter, and specific surface area, which provided some theoretical basis for practical engineering applications. The irregular porous models generated based on this method can be 3D printed by additive manufacturing and stereo imaging technologies.
