| Abstract: | The experiment research on the forming characteristics of hollow part with mandrel and without mandrel on 3-roll cross wedge rolling mill has been carried.Through finite element numerical simulation,deformation body's stress field,strain field and grain size in the forming process of hollow part with mandrel and without mandrel are compared and analyzed.It is indicated that the hollow part with equal inner diameter can be obtained through cross wedge rolling with mandrel,and grain size is more refine to satisfy the needs of shaft mechanics. |

| Keywords: | cross wedge rolling hollow part with equal inner diameter FEM grain siz |
