통계적 분석에 의한 마찰교반용접시 Al 6061 합금의 특성 및 강도 평가

Abstract

Recently, the energy-saving was growing up to interest of transporting machine filed because of globally environmental pollution problem. In this paper, welding of AL6061 alloy based on a representative sample of FWS(Friction Stir Welding) are proposed to characterize welding parameter`s relation by DOE(Design of Experiment) of statistical estimation techniques. It makes also high reliability data analysis and cost reduction up by applying for FEM(Finite Element Method). In this case, the control factors of welding of AL6061 alloy based on a representative sample of FWS are shoulder diameter, travel speed, and rotation speed of tool. And the impact of tensile strength on welding parameter analyzed using the each factor proceed with experiment by changing 3 stage level. Also, The effects that each variable has on the characteristic values were analyzed using the analysis of variance (ANOVA). And temperature field and von mises stress were obtained and valid of numerical analysis was verified by applying for SYSWELD.
