In this study, The damping property of vibration absorption device with disk springs and rubber rings was investigated using experiments and simulations. Friction forces of rubber rings were measured and the nonlinear relationships between forces and displacements of disk springs were obtained experimentally. The experimental results were compared with the theoretical results. Based upon the friction force and the energy dissipated by hysteresis of disk springs, damping models were presented. Combined damping model consisted of Coulomb damping of rubber rings and equivalent viscous damping constructed from hysteresis curve of disk springs was proposed. For practical use, equivalent viscous damping model constructed by energy loss per 1 cycle of response was suggested to investigate the damping property of vibration absorption device with disk springs and rubber rings of nonlinear properties.
