Abstract

This study addresses key challenges in modular construction, such as transportation and lifting limitations, by introducing a kirigami-inspired modular structure that folds into a compact flat-pack and deploys into a volumetric form. The research explores two pop-up kirigami kinematic (i.e.V-fold and sliding) mechanisms utilising thick panel material for modular structural elements. The study develops spatial linkage with degree-four vertices by implementing a thick panel axis-shift method, enabling transformation into volumetric forms through a single-degree-of-freedom actuation. The structural performance of the kirigami deployment pattern under service loads was evaluated using finite element modelling. Fibre-reinforced polymer was selected as the primary material due to its low self-weight and adequate structural properties, making it a viable alternative to conventional steel for deployable structures. Results demonstrated compliance with design standards for displacements, stresses, and global drift. Additionally, the inclusion of a locking mechanism significantly enhances the structural stability of the module by restraining any potential movement in its fully deployed state.

用于可部署体积模块化结构的厚板叽里格米的概念设计和结构分析

本研究通过引入一种可折叠成紧凑型扁平包装并展开成体积形式的 "气泡纸 "模块结构，解决了模块化建筑所面临的运输和吊装限制等关键挑战。这项研究利用模块化结构元素的厚板材料，探索了两种弹出式拼接运动学机制（即 V 形折叠和滑动）。该研究通过实施厚板轴移方法，开发了四度顶点的空间联系，通过单自由度驱动实现了体积形态的转换。研究采用有限元建模法评估了叽里格米展开模式在使用负荷下的结构性能。纤维增强聚合物被选为主要材料，因为它自重轻、结构性能好，可替代传统钢材用于可展开结构。结果表明，其位移、应力和整体漂移均符合设计标准。此外，通过在完全展开状态下限制任何可能的移动，锁定机制的加入大大增强了模块的结构稳定性。
