    A Novel Elastic Metamaterial with Multiple Resonators for Vibration Suppression by Saman Ahmadi Nooraldinvand, Hamid M. Sedighi, Amin Yaghootian

    Published 2021-01-01
    “…In this paper, two models of elastic metamaterial containing one and two resonators are proposed to obtain the bandgaps with the aim of providing broadband vibration suppression. The model with one DOF is built by assembling several unite cells in which each unite cell consists of a rectangular frame as the base structure and a rack-and-pinion mechanism that is joined to the frame with a linear spring on both sides. …”
