The vibrational response of multiple rotating circular plates, stacked together on a central spindle and coupled through stationary springs, is investigated. An analytical model is derived and a Rayleigh-Ritz approach employed in order to obtain the system’s modal response. Mode localization is shown to occur at all speeds of rotation for weakly coupled subcomponents and the degree to which the system exhibits localized behavior is shown to increase with rotation speed.
