Abstract:

Folded metamaterials are based on the development of folding structures and have extraordinary physical properties. ADAMS was used to analyze three typical structural models. Under the simple harmonic excitation of force and displacement, different crease stiffness affected the vibration response of Miura folded metamaterials. The results show that the Miura model with single-degree-of-freedom structure has a similar frequency response under two kinds of excitation, and the resonance frequency can be changed by changing the crease stiffness, which can achieve a good low-frequency isolation effect. The multi-degree-of-freedom model can reduce the resonance frequency by increasing the number of stack. It provides a theoretical reference for the vibration isolation design of Miura folding structure.
