A closed, elastic cylindrical shell is adopted as a simple model of the aircraft's fuselage. Several pairs of piezoelectric material, each with a closed electric circuit, are attached to the shell. The piezoelectric material serves as electromechanical dynamic absorbers for reducing the vibration of the fuselage and the subsequent interior sound pressure. In this paper, the equations of motion of the composite shell are derived. The vibration of the shell and the resultant interior sound pressure are analytically calculated. The absorbers are found to successfully attenuate the vibration of the shell and its interior noise. The effects of varying system parameters and absorber arrangements are studied and discussed.
