Evaluation of piezoelectric active control systems for vibrations suppression

The paper describes in progress research activities aimed at verifying the possibility of designing active vibration control systems based on piezoelectric devices. In particular a wholly clamped rectangular flat panel is mechanically excited and controlled with piezoceramic patches. Vibrations reduction tests and then correlations with numerical predictions, based on an integrated piezostructu...

Thickness Stretch Vibrations of Piezoelectric Ceramic Plates for Resonator Applications

The thickness stretch vibrations of piezoelectric ceramic plates are analyzed by solving the first-order Mindlin plate equations with finite element method in the twodimensional domain. The precise resonance frequency and distribution of displacements are obtained from the analysis in detail. The results based on the two-dimensional solutions are more important particularly in the evaluation of...

Torsional Vibrations of Nonhomogeneous

ABSTRACT. This paper is concerned with the torsional vibrations of a nonhomogeneous magnetostrictive elastic cylinder. The cylinder is subjected to the action of a circumferential magnetic field produced by an axial current of constant density and the deformation of a magnetostrictive cylinder is produced by a constant longitudinal magnetic field. The frequency equation is determined, and the d...

Power Electronic Devices for Damping Torsional Vibrations

Torsional vibrations and resonance problems with synchronous machines are most frequently encountered in rotor systems with long shafts and large inertias constituting a weakly damped mechanical resonator which exhibits a low resonance frequency. It is impossible to obtain a effective mechanical damping for these torsional vibrations, but by using a power electronics device and an inductive or ...
