Design and Wave Propagation Characterization of Starchiral Metamaterials
文献摘要：
Metamaterials with simple artificial topological properties made from industrially produced single-phase materials have extraordinary innovation and challenge.In this paper,we investigated wave propagation characteristics of a hexastarchiral lattice metamaterial with peri-odic assemblies and used the finite element(FE)method to study the band gap properties.Then,in order to understand the mechanism of band gaps,we discussed the mode shapes of unit cells and found that the bending of the ligament and the overall rotation have a high correlation with the generation of omnidirectional band gaps.The relationships between geometric parameters and band gap properties have also been systematically studied,which demonstrated that the band gaps of the proposed metamaterial could be reasonably predicted through the evolution of geometric parameters.Finally,the transmission characteristics of finite sandwich panel structures composed of periodic unit cells were calculated to verify the correctness of the band gap simu-lation results,which proved that the proposed artificial metastructure has potential application value in vibration and noise reduction projects.
