The paper concerns computer modeling and simulation of the roller burnishing process for machine part surfaces. For this purpose, a 3D application was developed in Ansys/Ls-Dyna to simulate physical phenomena occurring during the burnishing of rough surfaces at any given time. A physical, mathematical, and computer model of the process was developed. The results of strain and stress distribution as well as the depth of residual stresses are presented.Nowadays, automotive technology is developed at a very high level. Large corporations compete with each other by introducing newer, better, and innovative designs. More and more companies are emerging that offer engine power upgrades, improvements in traction, operational properties, and others. It should be remembered that the quality of manufactured products and their production costs are considered among the most important problems of modern manufacturing technology. Increasingly higher operational requirements are being placed on modern machine parts.
The reliability, strength, and durability of parts are decisively influenced by the properties of the surface layer, which are achieved depending on the type and course of the finishing process. Also, the diversity of applications and operating conditions create a need to seek such machining methods that allow for shaping different, yet optimal, product quality based on accepted criteria.
One such method is burnishing, which consists of local surface plastic deformation in a cold state using a hard and smooth (…)
