Abstract

Friction stir welding (FSW) is a well-established technique developed extensively over the past two decades for various applications. This study investigates the effect of repositioning the tool pin shoulder (0.18 mm) above the surface of a 12 mm thick dissimilar aluminum alloy (AA6063-AA5083) on tensile strength, welding temperature, and micro-hardness. Trials were conducted according to the L9 Taguchi method and further simulated using ABAQUS software. The input parameters spindle speed (SS), tool pin length (TPL), and traversing speed (TS) were each tested at three levels. The impact of these parameters on weld quality was analyzed using ANOVA. Optimization of the process to achieve desired temperature and tensile strength was carried out using grey relational analysis (GRA) for both experimental and simulated results. Mathematical models were generated using the multi-variable regression method (MVRM) and response surface method (RSM). Predicted data from the RSM model were compared to experimental outcomes, revealing a maximum deviation of 8.69% for temperature and 5.17% for tensile strength. Furthermore, the study demonstrated that ABAQUS accurately simulates the FSW process with an accuracy of up to 93.71%.

固态连接的多目标分析：工具销肩间隙对厚异种铝板的影响

搅拌摩擦焊（FSW）是一种成熟的技术，在过去二十年中得到了广泛应用。本研究探讨了在 12 毫米厚的异种铝合金（AA6063-AA5083）表面上方重新定位工具销肩（0.18 毫米）对拉伸强度、焊接温度和显微硬度的影响。试验按照 L9 Taguchi 方法进行，并使用 ABAQUS 软件进一步模拟。输入参数主轴转速（SS）、刀销长度（TPL）和移动速度（TS）分别在三个水平上进行了测试。使用方差分析法分析了这些参数对焊接质量的影响。针对实验和模拟结果，使用灰色关系分析 (GRA) 对工艺进行了优化，以达到所需的温度和拉伸强度。使用多变量回归法（MVRM）和响应面法（RSM）生成了数学模型。将 RSM 模型的预测数据与实验结果进行比较，发现温度和拉伸强度的最大偏差分别为 8.69% 和 5.17%。此外，研究表明 ABAQUS 能准确模拟 FSW 过程，准确率高达 93.71%。

期刊介绍： The objective of the Journal of Mechanics is to provide an international forum to foster exchange of ideas among mechanics communities in different parts of world. The Journal of Mechanics publishes original research in all fields of theoretical and applied mechanics. The Journal especially welcomes papers that are related to recent technological advances. The contributions, which may be analytical, experimental or numerical, should be of significance to the progress of mechanics. Papers which are merely illustrations of established principles and procedures will generally not be accepted. Reports that are of technical interest are published as short articles. Review articles are published only by invitation.
