In order to improve the vibration damping performance of bellows structures, a flat metal rubber as a damping element was developed.Through sinusoidal excitation sweep tests of bare bellows and its cladded structure with metal rubber, nonlinear dynamic behaviors including significant bending jump phenomenon, stiffness softening, and damping enhancement were characterized.A dynamic model of the vibration system was established based on the bilinear hysteresis model, by making linear equivalence on a single-degree-of-freedom delay system.The variable stiffness and damping characteristics of the bellows cladded structure with metal rubber were analyzed by means of the developed mechanical model.The experimental results show that the energy dissipation increases with the increase of the excitation frequency and the vibration amplitude within a certain range.The results provide an alternative theoretical and experimental method for the analysis of the vibration reduction of bellows structure systems in engineering applications.
