Abstract

In this study, multi-objective optimization for Friction stir welding of dissimilar AA2014-AA7075 has been presented to provide optimum tensile strength, hardness, and % of elongation. The input parameters considered for the analysis are tool rotational speed, feed, and tilt angle. Experiments are designed based on Taguchi L9 orthogonal array. Investigative analysis on the effect of input parameters on the responses is carried out using the MINITAB14 software package. The parametric influence on responses is discussed through the main effects plot. Further, multi-objective optimization is performed with the Technique for order of preference by similarity to ideal solution (TOPSIS). Results demonstrated that tool rotational speed is the most significant factor affecting the response followed by feed and tilt angle. The optimum cutting parameters obtained are tool rotational speed 710 rpm, Feed 30 mm/rev, and Tilt angle 2o.

基于TOPSIS法的AA2014-AA7075搅拌摩擦焊接工艺参数多响应优化

在本研究中，提出了异种AA2014-AA7075搅拌摩擦焊的多目标优化，以提供最佳的抗拉强度、硬度和伸长率。用于分析的输入参数包括刀具转速、进给和倾斜角度。实验是基于田口L9正交阵列设计的。使用MINITAB14软件包对输入参数对响应的影响进行了调查分析。通过主效应图讨论了参数对响应的影响。此外，利用TOPSIS方法进行了多目标优化。结果表明，刀具转速是影响响应的最重要因素，其次是进给和倾斜角度。获得的最佳切削参数为刀具转速710转/分、进给速度30毫米/转和倾斜角度2°。
