摘要

本研究通过实验和有限元分析阐明了焊缝位置对高级高强度钢定制焊接坯料(AHSS-TWBs)回弹行为的影响。AHSS-TWB 由 590Y 级高强度钢和 980Y 高级高强度钢制成,每种钢的厚度均为 1.2 毫米。通过气体钨极氩弧焊获得自生对接焊点。系统分析了三种不同的焊接线位置模式,以研究通过帽形拉弯产生的回弹现象。对 AHSS-TWB 的实验表明,焊缝位置会影响回弹。应力分布随焊缝位置的变化而变化,从而导致弯矩分量和相应的回弹角度的变化。根据焊接线位置的不同,各部件的回弹行为和弯曲力矩也不同。

Effect of weld-line position on springback behavior in advanced high-strength steel tailor-welded blanks on hat-shaped bending application

In this study, both experiments and finite-element analysis are performed to elucidate the effect of weld-line position on the springback behavior of advanced high-strength steel tailor-welded blanks (AHSS-TWBs). AHSS-TWBs are fabricated from grade 590Y high-strength steel and 980Y advanced high-strength steel, each with a thickness of 1.2 mm. Gas tungsten arc welding is performed to obtain autogenous butt-weld joints. Three distinct weld-line position patterns are systematically analyzed to investigate the springback phenomenon via hat-shaped draw bending. Experiments on the AHSS-TWBs show that the weld-line position affects springback. The stress distribution changes with the weld-line position, thereby initiating variations in both the components of the bending moment and the corresponding springback angle. Depending on the weld-line position, different springback behaviors and bending moments are resulted on the components.
