摘　　要：利用Pro/E三维CAD设计软件建模,导入ANSYS/LS_DYNA显式动力学有限元软件对无缝钢管轧制过程进行有限元数值模拟,分析无缝钢管截面的变形特点及轧制力和应力应变的变化规律。研究表明显式动力学有限元作为连轧无缝钢管轧制过程的分析方法是行之有效的,对生产实践有指导意义。A model was established using 3D CAD software Pro/E and then explicit dynamics finite element software ANSYS/LS-DYNA was applied to simulate the rolling process of seamless tube in order to study the deformation characteristics of tube section,the variation law of rolling force and strain-stress.It is indicated that explicit dynamics finite element method is effective in analyzing the continuous rolling process of seamless tube.
