Abstract: The forming process of light area reduction shafts by cross wedge rolling was simulated with the analysis software ANSYS/LS-DYNA.Surface and central qualities of light area reduction rolled pieces were analyzed in comparison with those of conventional area reduction rolled pieces.It is found that the ovality of the light area reduction rolled piece exceeds that of the conventional area reduction rolled piece under the same process parameter condition.Compared with the conventional area reduction rolled piece,the light area reduction rolled piece is more prone to central defects due to its both larger mean stress and maximum principal stress at the central point.Some measures to improve surface and central qualities of the rolled piece were proposed.Rolling experiments were carried out and the results demonstrate that forming light area reduction shafts by cross wedge rolling is feasible.
