Abstract
The rolling process of precision profile used for piston ring is simulated by large general-purpose explicit dynamic finite element analysis software ANSYS/LS_DYNA. The modeling of finite element models, the selection of material models and element types, the meshing of the model are introduced in detail. The rolling metal flow rulers of each pass are gained. The deformation of rolled piece and distribution of stress field are analyzed deeply. These can provide guidance for the design of forming roller and the optimization of process.
