Optimal control of thin circular cylindrical laminated composite shells using active constrained layer damping treatment

abstract

• Active control of the vibration of laminated circular cylindrical composite shells has been demonstrated using optimally placed patches of active constrained layer damping (ACLD) treatment. A finite element model has been derived to formulate the dynamics of the composite shells integrated with the patches of ACLD treatment. Optimal placements of the patches are determined by employing a modal controllability criterion to control the first two modes of vibration. The optimal size of the patches located at the optimal places has been determined on the basis of a frequency constraint. The performance of these patches in enhancing the damping of the symmetric cross-ply and angle-ply laminated shells has been illustrated with frequency response functions of the shells.
