Abstract

The application of retractable roof structures has enhanced the urban landscape, particularly in large-scale public buildings. Miura-ori is an immensely popular and highly inspiring method of paper folding. In this paper, three novel design families of retractable roof structures, integrating Miura-ori (and its variations) with scissor hinge units, are proposed. A concise overview of the concepts of Miura-ori (including its arched and fan-shaped variations), scissor joint unit, and rigid panel is first provided. Subsequently, coordinated motion conditions for the three proposed retractable roof structures are elaborately derived using geometric formulas, and the corresponding solutions are provided when the coordinated motion is not feasible. Lastly, after parameterizing the rigid-panel model, the motion mechanism of the retractable roof structures is analyzed exhaustively. The results indicate that all three new structures can achieve smooth opening and closing operations without motion interference. The proposed novel retractable roof structures enrich the variety of architectural structures and provide practical guidance for engineering applications.

折纸式可伸缩屋顶结构的发展与运动学分析

可伸缩屋顶结构的应用改善了城市景观，特别是在大型公共建筑中。Miura-ori是一种非常受欢迎且非常鼓舞人心的折纸方法。本文提出了三种新颖的可伸缩屋顶结构设计族，将Miura-ori（及其变体）与剪刀铰单元相结合。首先简要概述了Miura-ori的概念（包括其拱形和扇形的变化），剪刀接头单元和刚性面板。随后，利用几何公式详细推导了三种可收放顶板结构的协调运动条件，并给出了协调运动不可行时的解决方案。最后，在对刚性板模型进行参数化后，对可伸缩顶板结构的运动机理进行了详尽的分析。结果表明，三种新结构均能实现无运动干扰的平稳启闭操作。提出的新型可伸缩屋面结构丰富了建筑结构的种类，对工程应用具有实际指导意义。

期刊介绍： Meccanica focuses on the methodological framework shared by mechanical scientists when addressing theoretical or applied problems. Original papers address various aspects of mechanical and mathematical modeling, of solution, as well as of analysis of system behavior. The journal explores fundamental and applications issues in established areas of mechanics research as well as in emerging fields; contemporary research on general mechanics, solid and structural mechanics, fluid mechanics, and mechanics of machines; interdisciplinary fields between mechanics and other mathematical and engineering sciences; interaction of mechanics with dynamical systems, advanced materials, control and computation; electromechanics; biomechanics. Articles include full length papers; topical overviews; brief notes; discussions and comments on published papers; book reviews; and an international calendar of conferences. Meccanica, the official journal of the Italian Association of Theoretical and Applied Mechanics, was established in 1966.
