Abstract
Dynamic property of polyurethane foam is investigated experimentally. Polyurethane foam is loaded periodically with various amplitudes and various frequencies, and load, deflection and velocity of the polyurethane foam are measured. Using non-parametric identification technique in time domain, dynamic property of polyurethane foam is modelized as a function of velocity and deflection of polyurethane foam. Experiments are conducted with various condition of size of test piece and mount of compression, the dependence of the dynamic property on these parameters is investigated.
