Abstract
In this work we study the band gap formation in periodic rotors through modal and wave analysis. It is shown that band gaps are zones where no resonances appears, with a low vibration response, large bandwidth and where there is no propagating waves. The gyroscopic effect in the band gap formation is evaluated through a Campbell diagram and it is shown that the rotating speed does not significantly affect the band gap formation.
