The finite element model of cxoss wedge rolling stepped shaft was established by use of the AN- SYS/LS-DYNA software，and the cross wedge rolling process was simulated. Accordingly, the distribu- tion of the rolled piece in loth stress field and strain field at the stretching stage, the force condition and flow circumstanc es of the metal at the rolling deformation process were analyzed. The results sh+v that the stress of the rolled piece which is larger in the cole of the rollira, consists of biaxial tension and uniaxial compression; the strain is large in the thin rolled part and least in the cole, which decreases gradually from the outside to the inside. The deformation happened in both ends of the rolled piece and hardly in the mid- d1e, is symmetrically distributed. When rolling, the piece raclially compressed and axially extended; the maximmn strain shifted from the surface to the Cole.
