Original Abstract

The article shows results of the use of mathematical programming approach for nonlinear optimization problems to identify multi-parameter elastomer rheological models. The solution is based on the experimentally determined frequency dependent dynamic stiffness of the elastomeric parts. Measured waveforms of dynamic stiffness are approximated using multi-parameter rheological models. A generalized Kelvin model has been used for rubber silentblocks for automotive use. The nonlinear optimization methods have shown a significantly faster convergence and better accuracy of the calculation compared with the previously used classical non-linear Gauss-Newton least square optimization technique.
