摘要：

In this paper, Lagrangian formulation of a horizontal rotating beam with active constrained layer damping (ACLD) treatment is presented. The problem is approached by the Rayleigh-Ritz method. By assuming modal functions as the displacement shape functions and using effective damping model of the visco-elastic material (VEM) layer, the number of degrees of freedom? of the system is greatly reduced. The damping of the visco-elastic material is characterized by a shear (storage) modulus and a loss factor Also the dynamic behavior of the rotating ACLD beam is analyzed in the time domain. The affects of control gains, shear modulus and loss factor of the VEM on the dynamic response are also investigated.
