Abstract
Research has found that low-frequency broadband phononic crystals can effectively reduce vibration and noise. This paper proposes a method to broaden the bandgap of phononic crystals by adjusting the unit cell structure. Three-component phononic crystal unit cells were designed and optimized based on specific parameters. The study explored the effects of structural changes on the equivalent mass and bandgap characteristics of unilateral three-component and matrix-based five-component symmetrical structures. By transforming cylindrical scatterers into other shapes, the bandgap width was increased. This discovery is beneficial for broadening the bandgap without changing materials, which is advantageous for engineering applications.
