Abstract:In order to study the vibration characteristics of the functionally graded graphene platelets reinforced composite （FG-GPLRC） rotating cylindrical shell， the equivalent material properties of the graphene-reinforced structure were predicted based on the Halpin-Tsai micromechanical model and the composite inclusion theory， and the energy expression of the FG-GPLRC rotating cylindrical shell was derived using the first-order shear deformation theory. The traveling wave vibration characteristics of FG-GPLRC rotating cylindrical shell were analyzed by Rayleigh-Ritz method， and the kinetic equation was obtained. Then the traveling wave frequency was solved and the accuracy of the results was verified. The results show that the characteristics of the FG-GPLRC rotating cylindrical shell can be predicted in the 10-layer structure， and the traveling wave frequency can be significantly improved by the mass fraction of graphene platelets. In GPL-X mode， downlink wave frequency was the highest， while in GPL-O mode， traveling wave frequency increased with the increase of rotational speed. Under elastic boundary conditions， the frequency of traveling wave increased with the increase of axial half wave number.
