Abstract:The contact zone between roller and workpiece and its contour's definition are the cruxes of establishing the FEM mechanical model. On the basis of the study results of predecessors, this problem was solved rightly and a FEM simulation model of cylindrical workpiece power spinning, which conforms to the nature of the technology, was proposed and used to simulate the technology process, and the stress and strain distributions on the surface of workpiece were revealed.
Key words: power spinning finite element method model simulation analysis
