Numerical Simulation on Stamping of Laser Tailor Welded Blank

摘要: 用DYNAFORM软件对拼焊板成形过程进行有限元模拟研究。建立了盒形油箱零件的有限元模型,研究分析不同厚度、不同材料拼焊板的成形及焊缝对零件成形的影响。结果表明,以真实焊缝材料性能建立的焊缝模型能够较准确地描述拼焊板成形过程中的塑性变形及应变分布情况。Abstract: The stamping process of the tailor-welded blank was simulated by DYNAFORM software.The finite element model of a boxy part was founded,and the formability of tailor-welded blank with different thickness and material was studied.Meanwhile,the influence of weld seam on forming of the part was discussed.The results show that the weld seam model founded by real properties can describe the plastic deformation and strain distribution exactly in the forming process.
