Abstract: The optimal design and control of a rotating flexible arm with active constrained layer damping (ACLD) treatment are presented. The treatment is bonded to the beam structure and is an effective means for vibration suppression and control. The optimal PZT actuator thickness, viscoelastic layer thickness and storage shear modulus of the viscoelastic material (VEM) core are determined by maximizing a design objective function. Results are presented for the frequency response and impulse response of the beam tip under different control gains. It is found that the closed-loop response outperforms the open-loop one and also the derivative control is more effective in suppressing the vibration as compared to the proportional counterpart.
