摘要：
In this paper, based on the first order shear deformation theory, a vibration characteristic analysis model of a ring-supported composite laminated cylindrical shell structure under different boundary conditions was constructed by a wave-based method (WBM). The displacement scaling parameters, displacement matrix and force parameter matrix were 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 were derived. The accuracy of the established vibration characteristic analysis model was verified by comparing with the results of existing literature. A related parametric analysis study was carried out to investigate the influence of material parameters, geometric parameters, and ring support positions. © 2024 Chinese Vibration Engineering Society.
