Plastic Deformation Behavior of High Strength Cast Aluminium Cylinder in Hot Power Backward Spinning

Abstract:

The hot power backward spinning(HPBS) of the high strength cast aluminums (HSCA) cylinder is a complex metal forming process. To analysis the plastic deformation of HSCA cylinder in HPBS process, a 3D coupled thermo-mechanical FE model of the process was built under the ABAQUS/explicit environment based on the solution of several key techniques, such as heat boundary condition treating, material properties definition, ALE adaptive meshing technology, etc., and verified by theoretical evaluation. Then simulation and analysis of HPBS of the process were carried out. The results show that the strain gradient which leads to the serious inhomogeneous deformation is produced in the thickness direction of the workpiece during the process.
