摘要

In this paper,an active-passive control technology called as enhanced active constrained layer damping(EACLD)is applied to structural vibration suppression of a rigid-flexible coupled hub-beam system.The longitudinal shortening of the beam caused by the transverse deformation is considered so that the high-order geometrically nonlinear terms are obtained.By using the Euler-Bernoulli beam theory and describing the VEM with a complex shear modulus,and using the assumed mode method together with Lagrange's equations,the discrete high-order dynamic equations of the system with EACLD treatment are derived in the closed-loop case with a PD controller.Based on the new dynamic model,the dynamic behavior of the rotating EACLD beam is described in the time domain.The effects of coverage ratio of the control patch,mass of edge element,control gain and edge element location on the dynamic responses of the system are investigated.The results obtained show that the influences of edge element stiffness and mass can be helpful to designs of structural vibration control.
