Identification of simulation model of polyurethane foam by means of optimization algorithm

Popis výsledku v původním jazyce

Article deals with definition of phenomenological simulation model of polyurethane foam with open cells. This model describes the dependence of force responce on deformation and rate of deformation during uniaxial dynamical compression. Model definition comprises restoring force, viscose and frictional damping. The model has high number of constants therefore to find their values empirically has a limited use for simple phenomena what is exemplified for dynamically compressed specimen of foam by triangular course of deformation. For more complicated phenomena represented by compression load with random signal there the method of genetic optimisation algorithms for constants determination is used in this article . Finally the simulation error is quantified.
