To further explore the vibration characteristics of viscoelastic composite damping plates, the complex vibration differential equation of viscoelastic composite damping plates was derived based on the mechanics of composite materials, the first order shear deformation theory, a piecewise displacement model and the Hamilton′s principle. The theoretical solution satisfying the displacement boundary condition was obtained by the Navier method, and the theoretical solution was verified by finite element simulation. Finally, based on the verified theoretical model, the change rule of vibration characteristics of viscoelastic composite damping plate with the structural parameters were explored theoretically.
