·摘要：In this paper, low-frequency beam-like inertial amplification metamaterials (IAM) are investigated based on the local resonance theory. The inertial amplification mechanism is proposed to obtain the low-frequency bandgaps by altering the geometry parameters of the beam-like structures rather than changing the material properties (e.g. modulus, density etc.), which could reach to the first lower band gap than the traditional local-resonance structures. The band structures, frequency response curves, and the vibration modes of the beam-like structures are calculated and analysed by using the finite element method (FEM). The numerical results show that the first band gap of the structure ranges from 23 to 21 Hz. The frequency response curves are in accordance with those of the dispersion relationship. It is found that the interaction between the local resonance based on inertial amplification theory and the traveling wave modes in the proposed structure is responsible for the formation of the first band gap. This kind of IAM could provide an effective approach to obtain the low-frequency band gaps and could have many potential applications in the low frequency vibration reduction.
