Application of enhanced coulomb models and virtual tribology in a practical study

Abstract For the final quality of part, metal forming trends are depending on improvements friction and tribology. As a consequence, there is trend in which tribology becoming increasingly important for correctly replicating simulation those parts. The objective this work was to improve an automotive shell part AutoForm. provided by vehicle industry supplier. Enhanced Coulomb models consider change coefficient due different factors, better approximating description reality. current study, pressure velocity dependent were chosen as long combination both. virtual simulated using software TriboForm. Velocity model have shown similar results with expected lower coefficients friction.
