摘要

On the basis of the model of viscous compressible heat-conducting gas we study aeroelastic oscillations of a gas column in the acoustic resonator of the closed channel type; the oscillations are excited by an elastic element under the action of uniformly distributed load which harmonically varies in time. We compare spectra of oscillation power for the elastic element and gas column under periodic and quasi-periodic excitation.
