International Journal of Vehicle Design (IJVD), Vol. 43, No. 1/2/3/4, 2007

Abstract: This paper introduces an application of progressive collapse deformation structure that is called the Cylindrical Origami Structure (COS), which has the ability to absorb the shock of impact. The geometric analysis of COS is presented first. Then the characteristics of COS are further optimised using the most probable optimisation design. After that, the numerical models of COS are constructed and analyses are performed by using the finite element method. Finally, based on the optimised model, two kinds of subdivision scheme (Loop and Modified Butterfly) are employed to smooth the shape of it.
