摘要：
A cantilever beam with partially coated active constrained layer damping（ACLD）is taken as the object to study the simulation methods of two vibration reduction mechanisms involved in the vibration control technology. Firstly，by analyzing the force and deformation of the ACLD structure，the two vibration damping mechanisms of the viscoelastic layer and the piezoelectric layer's anti-phase retardation included in the ACLD vibration damping are described. Then，the viscoelastic shear deformation is expressed in the shape function and the piezoelectric retardative force is deduced by combining the piezoelectric equation and mechanical formula. The dynamic model of the ACLD treated composite beam with two kinds of damping mechanism iss established. Finally，an experimental study is carried out，and the simulation analysis results are verified through the ACLD cantilever beam vibration reduction experimental system. At the same time，the time-domain response of the composite beam when only a single damping mechanism including passive constrained damping or piezoelectric reversed phase blocking mechanism and ACLD processing is compared and analyzed. The results show that the maximum deviation between the simulation and experimental values is 18.6%，proving the rationality of the dynamic analysis model which contains two kinds of vibration damping mechanisms. Active constrained layer damping contains two kinds of damping mechanisms at the same time，so its damping effect is better than the other two vibration control methods which only contain a single damping mechanism. © 2023 Nanjing University of Aeronautics an Astronautics.
