Vibration suppression for laminated cylindrical panels with arbitrary edge conditions

摘要

Active vibration control of laminated cylindrical panels with arbitrary edge condition is investigated using piezoelectric fiber reinforced composite (PFRC) material. The boundary cases considered are free edge, simply supported edge and clamped edge for thin panels. Adopting a velocity feedback control strategy the transient response of cylindrical panels can be suppressed efficiently, and the relationship between the control gain and active damping ratio has been investigated. The active damping ratio curves are numerically calculated, and from the simulation results it is also found that the piezoelectric fiber orientation of the PFRC patches plays an important role in the vibration suppression capability.
