由于折纸在建筑工程中的巨大潜力，折纸因其可折叠和可展开而受到研究者的关注。然而，由于缺乏对厚度和重力方面的运动控制的系统研究，折纸在实际建筑工程中很少被用作结构。为了阐明折纸结构的提升过程，利用一个小比例尺的单自由度物理折纸模型进行了初步的折叠测试。折叠路径由非接触式测量系统和力-位移测量系统获得。通过对厚折纸的数值模拟，验证了实验结果。观察到了折叠过程与驱动力之间的不变量关系。此外，模型的最终构型与悬浮点的位置密切相关。提出了实现完全折叠的方法。并针对快速折叠结构的应用，对多单元模型进行了仿真。
ABSTRACT Origami have been focused on by the researchers for its foldability and deployability owing to the huge potential in architectural engineering. However, origami was rarely used in practical construction projects as structures due to the lack of systematic investigation of motion control with respect to thickness and gravity. To clarify the lifting process of the origami structure, a preliminary folding test is carried out with a small-scaled single-DOF physical origami model. Folding paths are obtained by the non-contact measurement system and the force-displacement measurement system. The experimental results are confirmed by the numerical simulation of thick origami. The invariant relationship is observed between the folding process and the driving force. Furthermore, the final configuration of the model is found to be strongly related to the location of the suspension points. The methods to realize the complete folding are suggested. Moreover, the multi-unit model is simulated aiming for the application of rapid foldable structures.
