Identification of rheological model parameters by means of nonlinear optimization in GAMS
Original language description
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 solverhas 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.
