摘要

标准木材弯曲方法要么是针对重复性优化的重工业工艺,要么是针对生产小规模产品的工艺技术。当代的研究集中在数字制造方法上,以克服几何限制和自动化自由形状的木结构,而不需要高度专业化的工艺。本研究的重点是机器人拉链弯曲,以实现具有结构特性的定制弯曲木件。该技术将切纹模式应用于两层平面木材元素上,以实现具有预先计算的弯曲和扭曲行为的压缩复合材料。本文描述了从最初的材料研究到实现机器人1:1结构安装的整个工作流程。所涉及的方法,如力学测试,几何找形,结构有限元模拟,数控机器人编程和三维扫描,描述了广泛的定性分析和定量数据。这项工作证明了机器人拉链弯曲的结构和几何能力在建筑行业的潜在应用,包括对未来研究发展的建议。

Robotic zip-bending of wood structures with programmable curvature

Standard wood bending approachesrely either on heavy industrial processes optimized for repeatability or on crafting techniques that are mostly intended for the production of small-scale products. Contemporary research focuses on digital fabrication methods to overcome geometrical limitations and automate freeform wood construction without the need for highly specialized craftsmanship. The presented research focuses on robotic zip-bending to achieve custom curved wood elements with structural properties. The technique uses kerfing patterns applied to two layers of planar wood elements to achieve a zipped composite with precomputed bending and twisting behaviour. The article describes the entire workflow from initial material studies to the realization of a robotically-made 1:1 structural installation. The involved methods, such as mechanical testing, geometrical form-finding, structural FEA simulation, CNC robot programming, and 3D scanning, are described with extensive qualitative analysis and quantitative data. The work demonstrates robotic zip-bending’s structural and geometrical capabilities for prospective applications in the construction industry, including suggestions for future research developments.
