摘要	Structural stiffness of phononic crystals (PnCs) can affect their bandgap properties. It thus needs to consider stiffness in the design of the unit cell of a PnC. In this paper, a local resonant (LR) rod composed of tri-wing rhombus ligament (TRL) resonators arranged periodically within a common hollow rod is proposed to create a low-frequency flexural vibration bandgap. The dispersion relations, mode of resonances and vibration transfer function are studied using a finite element method. Low-frequency forbidden bands can be effectively shifted by changing the resonator geometries. In addition, both numerical simulations and sample test are conducted to verify the low-frequency bandgap. The results show that the hollow rod with TRL resonators can create a low-frequency flexural vibration bandgap as well as have high support structure stiffness.
