Vibration suppression analysis for laminated composite beams embedded actuating magnetostrictive layers

This paper presents the analysis of vibration control of a laminated composite beam that including magnetostrictive layers. The formulation of problem is presented based on the shear deformation beam theory. For vibration suppression, the velocity feedback control with constant gain distributed is considered. Navier s method is applied to analyze the solution of vibration suppression of laminated beam with the simply-supported boundary conditions. The influence of lamination schemes, modes, number of smart layers at the structure, the control gain of the agnetic field intensity and smart layer position on suppress of the vibration are discussed. In addition, the  ntrolled motion of some special laminated composite beam is tested.
