Abstract

This study investigates the dynamical behavior of a cantilevered cylinder with local resonators subjected to both base excitation and vortex-induced vibrations (VIV). Local resonators are incorporated into the system to mitigate vibrations due to combined vortex interactions and periodic excitation. A comparative analysis is performed to assess the impact of various parameters, including the total mass of resonators and base excitation amplitude, on the nonlinear response of the beam. Additionally, resonators with distinct targeted frequencies are utilized to create broader attenuation regions, enhancing the suppression of vibrations due to combined vortex forces and base excitation.
