This study addresses the dynamic behaviors of a bearing supporting structure composed of rubber O-rings. To develop an analytical method to predict the dynamic properties of the O-rings without using any dimension-dependent experimental data, the viscoelastic behaviors of the material were modeled with Maxwell-hyperelasticity proposed by the authors. The viscoelastic model was implemented using the finite element method (FEM), and a dynamic analysis was performed, the results of which were compared with the experimental data. The influences of the dimensions, frequency, squeeze, and surface condition on the dynamic properties of the O-rings were clarified, and independent design parameters were determined. The values and distributions of hydrostatic pressure, principal strain, and viscous dissipation energy were also discussed.
