| Abstract | ||
| Traditional analyses of cylindrical shells often neglect spinning motion, treating them as static/quasi-static structures, which leads to deviations in vibration, stress, and stability assessments. Current research on moving loadinduced vibrations also overlooks spin rotation effects. This study investigates the time-dependent nonlinear dynamics of graphene-enhanced metal foam cylindrical shells (GPLRMF) with spinning motion. Using the firstorder shear deformation theory and Galerkin's method for discretization, we develop an analytical framework validated via comparative analyses and convergence checks. Numerical integration (Runge-Kutta method) reveals a counterintuitive phenomenon: increasing spin rotation reduces vibration amplitudes. The study systematically evaluates spin motion, geometric imperfections, and other parameters, providing design guidelines for rotating shells under transient loading. | ||
