金属板料成形极限的研究

A Research of Sheet Metal Forming Limit

摘要: 本文用M-K凹槽模型和倾斜凹槽模型,计算了不同材料性能参数的成形极限图,计算了不同应变路径对成形极限图的影响,并用双板实验的结果与理论计算结果进行了对比。实验与理论计算结果都表明,曲线应变路径对成形极限图有明显影响。因此,用实验方法绘制成形极限图时,必须保证应变路径的直线性。

Abstract: The M-K. groove model and inclined-groove model are used to calculate forming limit diagrams for sheet metal having difenent properties. The influence of different strainpaths on forming limit diagrams is analysed, A comparison is made between the results of calculations and double-plank experiments. The results, both experiments and calculations, show that curved strainpaths have obviouns influence on forming limit diagrams, so the linear strainpaths must be ensured when making forming limit diagrams experimentally.
