Abstract

Article deals with definition of model of mechanical properties of polyurethane foam with lumped parameters. The problem is considered from the car driver vibroisolation point of view. Model definition comprises restoring force, damping and frictional forces. It is verified for experimental results obtained from measurement of PU foam specimen with open cells. Apart from empirical way of model constants setting the optimization method of genetic algorithms is used for more simple phenomena.
