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 a
pproach employed in order to obtain the system's modal response. Mode
localization is shown to occur at all speeds of rotation for weakly co
upled subcomponents and the degree to which the system exhibits locali
zed behavior is shown to increase with rotation speed.
