摘要: 为了减小模具开发周期和提高产品成形质量,CAE软件在板材冲压成形数值模拟分析方面得到了广泛的应用。以某汽车底梁加固件为研究对象,采用Dynaform有限元软件、多工位多工序的建模方法对其进行了冲压成形全工序数值模拟,以FLD图为根据评判制件冲压成形质量,并对底梁加固件进行了级进冲压试验,结果表明数值模拟结果与实际试模效果比较符合,所获得工件厚度值的最大相对误差仅为2.94%,说明所建立的全工序级进冲压有限元模型是合理可靠的,能够有效地指导实际生产。

Abstract: CAE software in sheet metal forming has been widely used in numerical simulation analysis to reduce die development cycle and improve the quality of stamping products.The complete stamping process for stiffener part of automotive beam was simulated based on multi-step and multi-process modeling approach by using Dyanform software.The forming quality was analyzed depend on FLD.The progressive stamping test results of the stiffener part of automotive beam show that the simulated results are in accordance with the experimental results,the maximum relative error of the workpiece thickness is only 2.94%.The results prove that the complete stamping process finite element model established is reasonable and reliable,which can provide an effective guidance for the actual production.

Key words: stiffener of automotive beam, Dynaform software, complete process, numerical simulation
