Originální abstrakt

The paper presents results of the application of GAMS optimization software and CONOPT solver for nonlinear optimization problems to identify multi-parameter elastomer rheological models. The solution is based on the experimentally set 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 of a tractor cab mounting. The CONOPT solver has 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.
