Study of dynamic properties of flexible polyurethane foam

Experimental techniques for dynamic properties of flexible polyurethane foam used in automotive seats were described.In the experimental fixture a rigid block was mounted on a 3 cube of foam material,which served as the only flexible component. The dynamic system was molded as a single degree of freedom system. The experimental fixture was excited by a small impulse at the top of the block and by a shaker on the basement. For the first situation the foam was simplified as a linear viscoelastic material. By exciting with shaker the nonlinear and viscoelastic properties of foam materials were considered. For these two different cases the system response was measured and the corresponding system parameters according to the experimental data were identified.
