An automotive bushing is a device used in automotive suspension systems to reduce theload transmitted from the wheel to the frame of the vehicle. A bushing is a hollow cylinder, whichis bonded to a solid steel shaft at its inner surface and a steel sleeve at its outer surface. The relationbetween the force applied to the shaft and the relative deformation of a bushing is nonlinear andexhibits features of viscoelasticity. In this paper, an automotive bushing is regarded as nonlinearviscoelastic incompressible material. Instron 8801 equipment was used for experimental researchand ramp-to-constant displacement control test was used for data acquisition. Displacementdependentforce relaxation function was obtained from the force extrapolation method andexpressed as the explicit combination of time and displacement. Pipkin-Rogers model, which is thedirect relation of force and displacement, was obtained and comparison studies between theexperimental results and the Pipkin-Rogers results were carried out
