摘要：

研究了薄壁叉形环轴向辗压成形过程中等效应力、等效应变等变形场量与成形载荷的分布与演变规律。基于Deform-3D软件平台建立了薄壁叉形环轴向辗压成形的有限元仿真模型，提取了成形过程中的等效应力、等效应变等变形场量与成形载荷数据。结果表明，在薄壁叉形环轴向辗压成形过程中，随着变形量的增加，等效应力值与等效应变值逐渐增加，上筋与侧筋的等效应力值明显比下筋大，变形程度更高，锥模主要承受z向载荷，且随着变形量的增加逐渐增大，最大值为134 kN。通过揭示薄壁叉形环轴向辗压成形过程中的塑性变形规律，为实现薄壁叉形环轴向辗压成形提供了理论依据。

The distributions and evolution laws of the deformation field quantities such as equivalent stress and equivalent strain as well as the forming load during the axial rolling-forging of thin-walled forked ring were studied. Then, a finite element simulation model of the axial rolling-forging for thin-walled forked ring was established based on software Deform-3D platform, and the deformation field quantities such as equivalent stress and equivalent strain and the forming load data during the forming process were extracted. The results show that during the axial rolling-forging process of thin-walled forked ring, with the increasing of deformation amount, the equivalent stress and equivalent strain values gradually increase, and the equivalent stress values of upper and side ribs are significantly larger than those of lower rib, with a higher degree of deformation. The conical die mainly bears the z-direction load, which gradually increases with the increasing of deformation amount, with a maximum value of 134 kN. Thus, by revealing the plastic deformation law during the axial rolling-forging process of thin-walled forked ring, a theoretical basis is provided for realizing the axial rolling-forging of thin-walled forked ring.
