Dynamic analysis of graphene platelet-reinforced cylindrical shells subject to moving loads incorporating spinning effects

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 load-induced 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 first-order 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.
