Slab Method Analysis and FEM Simulation on Rotating Compression Forming of Cylinder Considering Coulomb Friction

Abstract:

An investigation into the compression forming of cylinder using the commercial code SUPERFORM is developed. The cylinder billet compressed between the upper and lower dies is meshed by a quadrangle elastic-plastic element. The numerical simulation based on the FEM also compares with the slab method established by us. In the slab method analysis, the stress distributions are estimated by considering the coulomb friction between the dies and the cylinder. Throughout this study, the effects of frictional coefficient, rotating angular speed, reduction and aspect ratio etc upon the compression force, the effective stress and the effective strain, and velocity field are discussed systematically. For verifying the validity of two models, comparisons of compression forces based both modes are carried out to prove the feasibility of both models.
