This study presents vibration analysis of a closed cylindrical shell and annular plate partially filled with the controllable fluids. The shell is connected with an annular plate clamped at the inner edge. The transverse plate displacement is taken in to account. The analysis will use the Kirchhoff-Love theory to describe the thin shell motion. The viscous model of external damping with the constant coefficient is assumed to describe the dissipation of the shell energy. Inside the main flexpline the closed cylindrical shell is axisymmetrically mounted, in such a way that the space between the shells is filled by the controllable fluid and the both annular ends are sealed. The analysed structure as a part of harmonic drive can generate vibration due to the wave generator operation. Assuming a harmonic single frequency excitation at the end x = 0 steady-state responses of dynamics equations are sought as harmonics with the same angular velocity. The fluid-filled laminated cylindrical shell and annular plate has shown an increased and controllable damping capacity as compared to the conventional shell.
