Abstract
In this paper, based on the first order shear deformation theory, the vibration characteristic analysis model of the ring-supported composite laminated cylindrical shell structure under different boundary conditions is constructed by wave based method(WBM). The displacement scaling parameters, displacement matrix and force parameter matrix are set by combining the wave function form as displacement variables. By combining the boundary condition matrices, the overall control equations of the composite cylindrical shell structure under ring support conditions are derived. The accuracy of the established vibration characteristic analysis model is verified by comparing with the results of existing literature. A related parametric analysis study is carried out to investigate the influence of material parameters, geometric parameters, and ring support positions.
