Controlling the Vibration Amplitude of a System with a Piezoelectric Element by Applying an Electric Voltage to it

The article is devoted to the study of mechanical response an electro-viscoelastic structure if electric voltage with given characteristics supplied a piezoelectric element attached surface structure. A cantilever plate made viscoelastic material considered as under study. amplitude displacements free end in resonance modes occurring at forced steady-state vibrations response. Excitation realized by harmonic movement applied clamped plate. control within framework this work supposed be performed supplying signal element. This changes harmonically and has form potential difference which according law. magnitude vibration determined numerically finite method implemented ANSYS software package. properties are described relations hereditary theory viscoelasticity terms complex dynamic moduli. Within work, between polarity were obtained. It shown that proper selection voltage, it possible vibrations.
