摘要 采用二维弹塑性有限元法分析了钢管的空拔过程;得到了变形区出口截面上的轴向应力分布,据此计算了拔制力;经实验证实,这种方法能够得到比较准确的结果,可以推广使用;此外,讨论了3个工艺参数(壁厚、摩擦系数和模锥角)与拔制力的关系,可为优化模具和管材拉拔工艺设计提供参考. The FEM of twodimensional elasticplastic is applied to analyze the forming process of nonmandrel pipe;the axial stress distribution at the end of deformation zone is obtained,based on which,the drawing force is calculated;compared with the experimental result,the method presented above can be used in practice.
