Abstract EN
A new two-dimensional locally resonant phononic crystal with microcavity structure is proposed.
The acoustic wave band gap characteristics of this new structure are studied using finite element method.
At the same time, the corresponding displacement eigenmodes of the band edges of the lowest band gap and the transmission spectrum are calculated.
The results proved that phononic crystals with microcavity structure exhibited complete band gaps in low-frequency range.
The eigenfrequency of the lower edge of the first gap is lower than no microcavity structure.
However, for no microcavity structure type of quadrilateral phononic crystal plate, the second band gap disappeared and the frequency range of the first band gap is relatively narrow.
The main reason for appearing low-frequency band gaps is that the proposed phononic crystal introduced the local resonant microcavity structure.
This study provides a good support for engineering application such as low-frequency vibration attenuation and noise control.
