| Outline of Final Research Achievements |
This study aims to apply foldable structures produced by origami theory to engineering and create new industrial innovation from Japan. As an example of applications, cylindrical foldable structures with torsional buckling patterns are herein treated to clarify their mechanical properties and investigate the functionality as vibration isolators.
As results of numerical computation, it was clarified that the structures had a displacement range in which the spring stiffness of the structures was quasi zero. Further computation and experiments revealed that the structures effectively mitigated vibrations in a wide frequency range and a peaky resonance never occurred.
