Popis:	This paper deals with the forced vibration of the aluminum beam using a piezoelectric actuator. Cantilever beam was excited by thin piezoelectric film placed near the fix support. The oscillation of the free end of the beam was measured using a laser displacement sensor. The beam's eigenfrequency and damping ratio for the first bending vibration mode was determined experimentally. The beam's deflection when the beam was excited by a piezoelectric actuator was also determined experimentally. The actuator was controlled by a signal generator and high-performance power supply and linear amplifier module for driving piezoelectric actuators. Data from experimental measurements were used to validate the finite element model of the beam with piezoelectric actuator. Results from experimental measurements and numerical simulations were compared.
