本文提出了一种新的实验方法来评估管材双向拉伸椭圆胀形的成形性。这一思想来源于椭圆形模具在成形极限曲线(FLC)右侧的液压拉伸试验。基于变形理论和经典的Hosford屈服准则,建立了管材液压成形椭圆形胀形的解析模型。设计了一种新型的椭圆形封头成形实验装置,该装置由5个上模镶块和1个下模镶块组成,并进行了实验研究。通过实验验证了不同应变状态下的线性应变路径,确定了QSTE340卷边焊管的塑性变形极限右侧。最后,理论结果和实验数据之间的比较。理论预测与实验结果吻合较好。
This paper proposes a novel experimental approach to evaluate the formability for tube hydroforming under biaxial stretching through elliptical bulging. The idea comes from the hydraulic stretch-drawing tests with elliptical dies for the right hand side of forming limit curve (FLC). Based on the deformation theory and the classical Hosford yield criterion, an analytical model is constructed for the elliptical bulging of tube hydroforming. Then the novel experimental device is designed with five upper elliptical die inserts and one lower die insert used to produce ellipsoidal bulged domes and some experiments are performed. The linear strain paths in different strain states are verified and the right hand side of FLC for roll-formed QSTE340 seamed tube is determined through the proposed experimental approaches. Finally, a comparison between the theoretical results and experimental data is performed. The theoretical predictions show good agreement with the experimental results.
