A folding analysis method of the origami structure for the construction control
As a sort of the foldable structures,the origami structure has received much attention in recent decades due to its continuity in the folding mechanism.It is believed to be rich for practical potentials in various fields.The folding process of the origami model has been simulated taking the folding angles as the basic parameters.However,for the practical usage in the field of building engineering,the external forces at the vertices of the origami structures are often significant,such as the driving force and the gravity.In such case,the deforming process can be hardly traced by the traditional methods anymore.The present paper proposes a methodology for tracing the folding process of the origami in three-dimensional space,aiming to control the deforming procedure of the foldable structure.This method controls the nodal coordinate directly in the origami model activated by the external force on the vertices.The deforming path is obtained through the algorithm based on generalized inverse theory.In order to simulate the practical construction condition,the external force on the nodes are adjusted concerning the gravity and the disturbance.The proposed method is demonstrated through the numerical examples,focusing on the deployment of a foldable structure on the basis of the Yoshimura-Ori pattern.The method proposed in the paper is believed to be feasible in analyzing the folding mechanism of origami structures for in the construction process.
