本文对正-反-径向挤压过程进行了分析。采用有限元方法研究了模具圆角半径、间隙高度等几何参数以及摩擦力等工艺条件对成形过程的影响。使用ABAQUS软件进行有限元模拟。将有限元计算结果与实验结果进行了比较，分析了不同区域的成形载荷和材料流动情况。产品纵向横截面的硬度分布也用于验证有限元分析获得的应变分布。理论计算结果与实验结果的比较表明，两者吻合较好。硬度与应变值之间的关系与以前的工作是兼容的。
This paper presents the analysis of forward–backward-radial extrusion process. Finite element method has been used to investigate the effect of geometrical parameters such as die corner radius and gap height as well as process condition such as friction on the process. ABAQUS software is used for finite element simulations. The finite element results are compared with experimental data in terms of forming load and material flow in different regions. Hardness distribution in longitudinal cross-section of the product is also used to verify strain distribution obtained from finite element analysis. The comparison between the theoretical and the experimental results show good agreement. The relation between hardness and strain value is compatible with previous work.
