摘　　要：两轧辊在轧制区的轧制力不对称性是偏心轴类零件两辊楔横轧轧制成形的一个显著特征.利用有限元法计算了偏心轴类零件楔横轧成形中轧制区轧制力差,并对其影响因素进行了较为系统全面的分析,阐明了影响因素对轧制力差的影响机理,最后还综合分析了各影响因素对轧制力差的影响程度.In the rolling procedure of eccentric shafts by cross wedge rolling, the non-symmetry of rolling force in rolling zone is a significant characteristic. The force difference in rolling zone of eccentric shafts during cross wedge rolling was calculated by finite element method and its influencing factors were systematically analyzed. The mechanism of influencing factors on the force difference was clarified. Finally the influence degree of each influencing factor was evaluated.
