拉伸/收缩翻边过程的修边线预示

DETERMINATION OF TRIMMING LINE FOR STRETCH/SHRINK FLANGING

  • 摘要: 本文基于全量塑性理论及膜应变假设,导出了一种新的拉伸/收缩翻过数学模型。该模型考虑厚向(平均)各向异性系数R对翻过高度的影响。通过与过去的理论研究和实验结果相比较,证实本文所提出的方法能较精确地预示出修边线位置。

     

    Abstract: In this paper a mathematical model for stretch/shrink flanging is developed based on the total strain theory and membrane assumption The influence of average normal anisotropic coefficient R on the flanging height can be considered in this model. The results of this model are compared with those of other theories and experiments, showing that this model gives accurate trimming line prediction.
