Modelling of Damping Force of Dynamically Loaded Specimen of Polyurethane Foam in Dependence on Its Density

Received17 Jun 2010
Accepted17 Jun 2010


Article deals with measurement and modelling of damping force of polyurethane foam specimen being compressed. The specimens were taken from car seats and differ by material density. For modelling of damping force during harmonical kinematical excitation the explicit formula is used. Its parameters are found by means of method based on evaluation of energy dissipated during one loading cycle and also on evaluation of position of damping force extreme.
