摘要

In this study, upset forging of ring were conducted for contact interfaces with and without lubricants. The surface topography of dies and specimens formed patterns of concentric curves and parallel lines with different levels of roughness. Various uneven boundary frictional conditions were generated using combinations of dies and specimens with different surface conditions. Based on the experimental results, an anisotropic frictional model governing upset forging problems was established and applied in finite element analysis software (DEFORM-3D). The analysis results include the predictability of the anisotropic friction model and the adequacy of finite element analysis results.
