摘要
本论文研究了不同焊接方法、接触配置和厚度差异对铝合金拼焊板成形性能极限拱顶高度(Limiting dome height,LDH)值的影响,并采用Taguchi方法对3种影响因素进行了分析。结果表明:对于异种厚度的铝合金拼焊板,Face配置时的LDH值要小于Root配置时的LDH值,与焊接方法无关;激光焊接的LDH值要小于搅拌摩擦焊接的LDH值,与配置方式无关。对于同种厚度的铝合金拼焊板,LDH值都大于异种厚度时的LDH值,与配置方式无关;且Face配置时的LDH值仍然小于Root配置时的LDH值。厚度差异是影响铝合金拼焊板LDH值最主要的因素,接触配置对LDH值的影响较小,对LDH值影响最小的是焊接方法。
In this paper, the effects of the different welding methods, contact configuration and thickness differences on the formability(Limiting dome height, LDH) value of aluminum alloy tailor welded blanks were studied, and the three influencing factors were analyzed with Taguchi method. For the aluminum alloy tailor welded blanks with different thickness: the LDH of Face configuration is less than that of Root configuration, and has nothing to do with the welding method;the LDH of laser welding is less than that of friction stir welding and has nothing to do with the configuration. For the aluminum alloy tailor welded blanks with the same thickness: the LDH is higher than that of the different thickness, regardless of the configuration;the LDH in Face configuration is still smaller than that in Root configuration. The results show that the thickness difference is the most important factor affecting the LDH value, the contact configuration has slight influence on the LDH value, and the welding method has the least influence on the LDH value.
