Based on the nonlinearity of metal rubber components and its different elastic damping mechanical properties with different structures, the mechanical model of hysteresis loop boundary deformation process of metal rubber components with different relative densities was established by the experiment method combining theory. Dynamic characteristics of metal rubber damping ring were analyzed under harmonic excitation load and experimental study was conducted. The elastic damping performance of the damper with preliminary deformation was researched and the experimental result showed good agreement with the theoretical analysis one, which provides a theoretical basis for practical application of this kind of damper.
