| 中文摘要: |
| 论文利用刚性折纸结构折叠和展开运动中板面无应力这一特点，计算分析“Miura”折纸模型的几何构型，得到“Miura”折纸模型的几何构型的一般规律，基于该规律，设计一种新颖实用的可折叠建筑结构形式。该结构形式提供一个具有多个独立维度的矩形庇护空间，具有较好的伸缩性和适应性；建立该结构的物理模型，测试其折叠展开过程的运动可行性，并通过非线性有限元软件ABAQUS计算分析，得到该结构在完全展开状态下结构行为的分析结果。 |
| 英文摘要: |
| According to the characteristics of no stress on the plate in the folding and unfolding movement of the rigid origami structure, the geometric structure of the “Miura”origami model is calculated and ageneral rule is obtained. On the basis of the rule, a new and practical architectural folding structure is designed. It provides a rectangular shelter with multiple independent dimensions with good scalability and adaptability. Then, a physical model is established to test the feasibility of movement in the folding and unfolding process. Through the computation and analysis with the finite element software ABAQUS, the analytical result of the structural behavior is obtained in its completely unfolded state. |
