起皱是板料成形过程中的主要缺陷,起皱的数值模拟作为解决起皱问题的有效方法,越来越受到工业界和学术界的重视。本文利用大型非线性有限元软件ANSYS/LS-DYNA的动态显示算法,对低碳钢冷轧板杯形零件在冲压过程中发生的起皱现象进行数值模拟及实验研究,分析了不同坯料尺寸和不同变形工艺条件下的变形过程。结果表明,模拟结果与实验结果基本吻合,数值模拟结果可靠,具有良好的应用价值。 Wrinkling is the main defect in sheet metal forming process. As an effective method to solve the wrinkling problem, numerical simulation of wrinkling has drawn more and more attention from industry and academia. In this paper, we use the dynamic display algorithm of large-scale nonlinear finite element software ANSYS / LS-DYNA to simulate the wrinkling phenomenon of cup-shaped parts of cold-rolled low carbon steel during stamping. The effects of different blank sizes and Deformation under different deformation conditions. The results show that the simulation results are basically consistent with the experimental results, the numerical simulation results are reliable and have good application value.
