By the use of the precise displacement controlling of the material testing machine, static and dynamic tests of ring metal rubber elastic cells had been done, the result indicated that metal rubber material had obvious hysteresis nonlinear feature. High order elastic complex damp is constructed using hysteresis curve fitting decomposition. The model is constructed using a nonlinear combination of dynamic nonlinear stiffness and dynamic nonlinear complex damping mechanisms. The parameters in the model are identificated from the experimental hysteresis data. The force vs displacement hysteresis curve are reconstructed using the model with these identificated parameters. The results show that the model captures the nonlinear vibration system behavior quite accurately and the proposed method is practicable for modeling of a nonlinear vibration system with hysteresis characteristics.
