| Abstract: | The friction force between a steel roller sliding on a plane polyurethane sample under low normal loads has been analytical evaluated. The analytical model is based on the Hertzian elastic deformation between the roller and a plane polymer operating at low normal loads. Based on the friction experiments realized with a Tribometer CETR UMT-2, were determined the friction forces and friction coefficients for various normal loads and sliding speeds. The elastic modulus of the polyurethane was experimentally determined by curve fitting of the indentation curve obtained also with the Tribometer CETR UMT-2. By using experimentally relations for variation of the friction coefficient with roller – polyurethane contact pressure and for variation of the elastic modulus of the polyurethane as function of normal load, a complex equation for the friction force in roller-polyurethane sliding contact has been developed. The analytical model has been verified by the experimental results. |
