厚度和重力是折纸结构在建筑施工领域面临的重要问题和挑战。本文提出了一种数值折叠分析方法，利用可动框架结构模型研究了在外力作用下厚折纸的运动特性。折叠分析的数值方法基于广义逆理论。因此，通过直接引入节点力，可以得到重力环境下的变形模式和折叠路径。提出了一种利用运动框架建立厚折纸模型的通用建模方法。为了验证所提出的方法，对单自由度和多自由度实例进行了研究。得到了在外力作用下的折叠过程，并讨论了其刚性运动模式。该方法对厚折纸的折叠过程进行了可行性分析，为今后实际的快速施工任务评估提供了依据。
Thickness and gravity are both the significant problems and challenges for origami structures in the field of building construction. This paper described a numerical folding analysis method to investigate the kinematic characteristics of thick origami using movable frame structural models driven by the external forces. The numeric methodology of the folding analysis is based on the generalized inverse theory. Therefore, both the morphing modes and the folding paths can be obtained in the environment of gravity through introducing the nodal forces directly. A general modeling approach is proposed to establish thick origami models using kinematic frames. To demonstrate the proposed method, single-DOF and multi-DOF examples are investigated. The folding procedures are obtained under the external forces, and the rigid motion modes are discussed. The presented method shows feasibility of analyzing the folding process of thick origami, which can help assess the practical rapid construction tasks in the future.
