Current Trends in PZT Control of 2D Cylindrical Panels Made of Advanced Materials – Dynamic Instability and Wave Propagation

The paper presents a methodology for the passive and active displacement and vibration damping of beams and multilayered composite cylindrical shells. The displacement suppression systems consist of piezoelectric extension actuators bonded to the external surface. The second solution applies piezoelectric shear actuators/sensors embedded in the structure, An analysis on active vibration control of smart laminated cylindrical shells based on Hamilton’s principle and the higher order deformation theory is discussed. Then, the investigated cylindrical structure is modelled using two different approaches: solutions with the aid of series with the use of numerical symbolic package Mathematica and finite element NISA II models. Active vibration suppression is implemented with positive position feedback (PPF) and velocity feedback. The non-local formulation shows the influence of governing relations on eigenfrequencies. The effects of the position of the piezoelectric actuators on shell structures is demonstrated .
