论文摘要
弹性地球网格(EGG)是轻巧的结构,可以轻松部署到近似设计器提供的自由形式表面。但是,在初始配置中,网格在部署过程中非常平坦,但是,曲率会诱导到结构,因为网格元素弯曲和扭曲。它们的布局是几何发现的,它基于自由形式设计曲面上的地球曲线网络。用这种方法生成布局,将弹性基因机制编码为在部署过程中创建弯曲形状的网格。在最终状态下,网格可以固定以支撑并用于各种目的,例如自由形式的子结构,镶板,阳光和雨水保护器,展馆等。但是,到目前为止,这些结构仅使用小规模桌面模型进行了研究。我们研究了此类结构的可伸缩性,并提出了一个中等大小的模型。它是由建筑专业的学生设计的,没有有关弹性结构或差异几何形状的专家知识,仅使用弹性地理网格设计pipeline。我们进一步提出了用于鸡蛋模型的制造过程。它们可以快速建造,预算较小。
Elastic geodesic grids (EGG) are lightweight structures that can be easily deployed to approximate designer provided free-form surfaces. In the initial configuration the grids are perfectly flat, during deployment, though, curvature is induced to the structure, as grid elements bend and twist. Their layout is found geometrically, it is based on networks of geodesic curves on free-form design-surfaces. Generating a layout with this approach encodes an elasto-kinematic mechanism to the grid that creates the curved shape during deployment. In the final state the grid can be fixed to supports and serve for all kinds of purposes like free-form sub-structures, paneling, sun and rain protectors, pavilions, etc. However, so far these structures have only been investigated using small-scale desktop models. We investigate the scalability of such structures, presenting a medium sized model. It was designed by an architecture student without expert knowledge on elastic structures or differential geometry, just using the elastic geodesic grids design-pipeline. We further present a fabrication-process for EGG-models. They can be built quickly and with a small budget.
