Abstract
From the viewpoint of the pedestrian protection and the light collision in the car, it is effective to make deformation quantity large under the small load. In order to increase deformation quantity of axis crash problems, it is important how to make beautifully folded patterns. Therefore, in this research, on the basis of the principle of the origami engineering, several kinds of completely foldable structures were proposed. In addition, the characteristic of the proposed structures were analyzed by using finite element method simulation and optimized by the method of response curved surface method.
