中文摘要:
      借助有限元模拟软件ANSYS/LS-DYNA对304不锈钢线材椭圆孔型两道次冷连轧过程进行三维弹塑性有限元模拟，得出轧件在轧制过程中的等效应力、应变、金属流动、宽展等结果。模拟所得轧件的宽展与实验值的对比证实了利用有限元软件ANSYS/LS-DYNA进行模拟的可靠性。
英文摘要:
      This paper presents details of numerical simulation on the two pass continuous cold rolling of oval profile 304 stainless steel wire with the aid of FE code ANSYS＼LS-DYNA. The equivalent stress, metal flowage, equivalent strain, spread coefficient ratio of the workpiece which provide theoretical guidance to actual production are gotten. The comparison of simulation spread coefficient ratio with experiment data shows good agreement, which confirms the reliability of ANSYS/LS-DYNA in analyzing problems of shape rolling.
