On the basis of nonlinear FEA code ANSYS/LS-DYNA, rail rolling process of universal rolling unit were simulated by 3D large deformation thermal-mechanical coupled elastic-plastic FEM. And the deformation shape of the work piece, deformation parameters and cross dimensions for each pass were obtained and stress,stain distribution and metal flow in rolling process of typical passes were analyzed in detail. Analyzed typical pass stress and strain distribute, rolling stress and deforming in universal pass last groove in detail,discussed the effect regularity of residual stress distribution and size to safely using rail, detailed to expound universal pass to railhead tread circular arc process.
