Testing of piezofilms for actuation and active control of blade flexural vibration

Popis výsledku v původním jazyce

For our laboratory tests the PVDF films and PZT patches give a possibility to excite the flexural vibration of the of blades within the bladed disk by time continuous forces independently of the rotor revolutions. In addition the piezoelectric foils could be used as the actuators for the vibration control of the blade vibrations, too. Therefore several dynamic experiments of the clamped model blade equipped with PVDF films were performed for the force description of the piezo foils and their behavior asactuators of the blade vibration. As a reference source of excitation the electromagnet was installed against the end of the blade. The FE beam model was used first for the calibration of the film bending moment with respect to supply voltage from the amplitudes of the blade forced resonant vibration. This model was also utilized for numerical analysis of the vibration suppression effects both by additional parametric excitation and by active damping. For low level of forced vibration a
