Resonance Vibration and Dissipative Heating of a Flexible Viscoelastic Beam with Piezoactuators in the Presence of Shear Strains

Resumo

We consider a problem of forced resonance vibration and dissipative heating of a hinged flexible viscoelastic beam with piezoactuators in the presence of transverse shear strains. The effects of geometric nonlinearities, in-plane shear strains, and the conditions of heat exchange on the surfaces on the amplitude and temperature-frequency characteristics of the forced vibration of the beam and the thermal failure of the system are investigated. The possibility of active damping of the mode of flexural vibrations by piezoactuators is analyzed.
