Analyses of Profile Radial-Axial Ring Rolling Process Based on Explicit Finite Element Method

Profile radial-axial ring rolling is a complex bulk forming used to produce seamless rings for critical structural components in many industries, such as machinery, aeronautics, energy and automotive. The process is characterized by high nonlinearity, unsteady three-dimensional deformation, dynamic contact boundary conditions caused by the rotations of ring and rolls. In this paper, a numerical model based on explicit finite element approach is proposed to simulate and analyze the process. An expanded ring with profile section has been obtained by numerical simulations with the dynamic model based on explicit finite element method.
