摘要

摘要: 运用数值模拟的方法并结合胀形试验分别研究了同质差厚拼焊板在不同板厚比以及异质等厚拼焊板在不同强度比情况下，焊缝参数对拼焊板成形能力的影响规律，确定了焊缝对拼焊板成形能力产生主要影响的板厚比及强度比范围。结果表明：焊缝对拼焊板成形能力的影响是具有一定母材匹配范围的。当板厚比或强度比小于1.3时，焊缝是影响拼焊板成形能力的主要因素，应从改善焊缝性能方面着手提高拼焊板成形能力；当板厚比或强度比达到或大于1.3时，母材差异程度是影响拼焊板成形能力的主要因素，应从合理搭配母材以及优化成形工艺方面着手设计拼焊板。

Abstract: The influence of the weld seam parameters on the formability of tailor welded blanks (TWBs) with same material and different gage under different base material thickness ratio as well as different material and same gage under different strength ratio was studied with numerical simulation techniques combining with the dome test, and to determine the thickness ratio and strength ratio of weld seam as the major effecting factor on formability of TWBs. The results show that the influence of the weld seam on the formability of TWBs has a matching scope of the base. At the thickness ratio or strength ratio of base below 1.3, the weld seam is the major effecting factor on formability of TWBs, and which will improve the property of weld seam so as to enhance the formability of TWBs. At the thickness ratio or strength ratio of base above 1.3, the deviation level of base is the major effecting factor on the formability of TWBs, and which will be reasonable for combining the base with the processing optimization of TWBs.
