| 摘 要： | 根据钢管斜轧过程的变形特点,利用ANSYS/LS-DYNA有限元软件对Accu-Roll轧管机热轧奥氏体无缝钢管的轧制过程进行有限元数值模拟.通过模拟仿真计算,分析无缝钢管截面的变形特点及轧制力和应力应变分布的变化规律,通过将模拟结果与实测数据进行比较,验证了模型的可靠性.模拟结果表明,在轧制过程中孔型形状不当易造成双鼓形,整个轧制过程中最大轧制应力为403.4 MPa,最大等效应力值为231.8 MPa.

| Abstract: | Based on the deformation characteristics of steel tubes in the process of skew rolling,finite element software ANSYS/LS-DYNA was applied to simulate the rolling process of hot-rolled austenitic seamless steel tubes by Accu-Roll pipe mill.The deformation characteristics of tube section and the variation law of rolling force and strain-stress were obtained by finite element analysis.The simulation results were compared with the measured data,and the model was proved to be reliable.The results of simulation show that the unfitted shape of pass can bring out the overlap;during the rolling process,the maximum rolling stress is 403.4 MPa,and the maximum equivalent stress is 231.8 MPa. |
