Vibration control of composite shells using embedded actuating layers

摘要

Analytical solutions of laminated composite shells with embedded actuating layers are presented in this study. The magnetostrictive actuating layers are used to control natural vibration of laminated composite shell panels. The first-order shear deformation shell theory (FSDT) is used to represent the shell kinematics and equations of motion. The exact solution for symmetric laminated shells with embedded actuating layers under simply supported boundary conditions is obtained using the Navier solution procedure. Negative velocity feedback control is used. The parametric effects of the position of the rnagnetostrictive layers, material properties and control parameters on the vibration suppression are investigated in detail.
