Elastomeric bushings are essential components in tuning vehicle suspension systems. A nonlinear viscoelastic force-deformation relation, which is computationally convenient for use in multibody dynamics simulations of automotive suspensions, is presented. This force-deformation relation extends a single mode force-deformation relation to include coupling effects due to combined radial-torsional deformations. The relation contains a force relaxation function, which is dependent upon the radial displacements and angular rotations imposed on the bushing. The relaxation function is constructed using experimental results from bushing tests under radial, torsional and coupled radial-torsional deformation modes. It is shown that the predictions of the proposed relation are in good agreement with experimental results.
