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.

摘要：

折叠超材料基于折叠结构发展而来，具有超常的物理性能。应用ADAMS分析典型的三种结构模型，在力和位移两种简谐激励下，不同折痕刚度对Miura折叠超材料振动响应的影响。结果表明，单自由度结构的Miura模型在两种激励下频率响应类似，通过改变折痕刚度可以改变其共振频率，达到很好的低频隔振效果。多自由度模型可以通过增加堆叠数量降低共振频率。为Miura折叠结构的隔振设计提供一定理论参考。
