摘要：
In a structure with constrained damping，the middle viscoelastic layer mainly depends on the staggered motion of the substrate and the constrained layer to produce shear deformation and dissipate energy，so an effective approach for introducing interlayer deformation relationships is necessary to improve modeling accuracy. Therefore，the finite element method is used to investigate the dynamic modeling method of cylindrical shell with partial constrained layer damping. Firstly，based on Donnell's thin shell theory，the stiffness and mass matrices of the composite element are derived by considering the deformation relationship between each layer. Next，a transition element is constructed to connect the composite shell element and the single layer element with only substrate，and the effective assembly of the total stiffness and total mass matrices for cylindrical shell structure with partial constrained layer damping is realized. Furthermore，considering the elastic constrained boundary conditions of composite cylindrical shell，the motion equation of composite shell is determined，and the formula for solving its vibration characteristics is provided. Finally，a case study is conducted to verify the accuracy of the proposed finite element model by comparing it with experimental and ANSYS simulation results. The influence of thickness on both constrained layer and viscoelastic layer on the vibration and damping characteristics of composite cylindrical shell are further analyzed. © 2023 Nanjing University of Aeronautics an Astronautics.
