Abstract

A retractable roof is a structure that can move or fold to open or close a covered area. Detailed static and dynamic analyses of an innovative Miura-ori inspired retractable roof structure are investigated using the finite element parametric modeling method. Essential geometric parameters (such as the acute angles of parallelograms, the shape of the parallelogram panels, and the number of scissor joint units) are parameterized to investigate the mechanical properties of the structure in various geometric configurations under three distinctive operational states (completely folded, half-opened, and fully open). Initially, a static performance analysis of this innovative retractable roof structure is conducted. Subsequently, studies of the instability modes and parametric static stability performances in different states are examined. Finally, the basic natural frequency characteristics and the parametric dynamic stability of the structure in various states are performed. The preliminary mechanical analysis indicates the Miura-ori inspired retractable roof is a viable structural system. Additionally, the parametric analysis results herein offer guidance for further investigation and real-world implementation of this novel roofing system.

Miura-ori启发式可伸缩屋顶结构力学性能研究

可伸缩屋顶是一种可以移动或折叠以打开或关闭覆盖区域的结构。采用有限元参数化建模方法，对一种创新的Miura-ori启发的可伸缩屋顶结构进行了详细的静力和动力分析。通过参数化基本几何参数（如平行四边形的锐角、平行四边形面板的形状和剪刀接头单元的数量），研究了三种不同操作状态（完全折叠、半打开和完全打开）下不同几何构型下结构的力学性能。首先，对这种创新的可伸缩屋顶结构进行了静力性能分析。随后，对不同状态下的失稳模态和参数静稳定性能进行了研究。最后，计算了结构在各种状态下的基本固有频率特性和参数动态稳定性。初步的力学分析表明，Miura-ori启发式可伸缩屋顶是一种可行的结构体系。此外，本文的参数分析结果为这种新型屋面系统的进一步研究和实际应用提供了指导。
