摘要

The Bloch theorem and finite element technique are applied to investigate the bandgap property of trigonal chiral cellular, which is illustrated through band diagrams. The finite element model is developed to validate the results. Vibration transmission displays significant attenuation for the frequency located in the band gap. The distribution of the band gap is determined by the geometry of the unit cell and can be tuned to specific frequency range. Attention is devoted to the dependence of phase speed and group velocity on frequency and direction, which provides important information about anisotropic wave behavior of the structure and shows existence of preferential directions of propagation and energy flow. The research outcomes will lay a solid theoretical base for the designing of chiral isolation structures.
