Title: 139 On the Dynamic Properties and Modeling of Nonlinear Viscoelastic Materials
Abstract: Rubber isolators are used for decreasing engineering vibration and noise. Many of rubber isolators are cross-linked rubbers filled with filler such as carbon black. The dynamic behaviors of the rubbers are nonlinear. It is difficult to analyze the nonlinear dynamic behaviors. We measured dynamic properties (storage shearmodulus, loss shear modulus, loss factor) of SBR filled in carbon black under various conditions of strains andfrequencies. In this paper, mechanical model composing of linear springs and linear dashpots and sliders is applied to dynamic behaviors of the rubber.
