摘要
利用有限元分析软件ANSYS,对钢铜异种金属焊接接头处铝焊缝的残余应力进行了有限元模拟分析,得出影响焊缝残余应力的因素。设置了多组对照试验,分别分析了平板厚度、焊缝以及对流系数等因素对残余应力的影响。结果表明,利用ANSYS软件在一定范围内可以比较准确地模拟出焊接应力场的情况,对焊接过程的研究有一定的参考价值,进而为制定合理的焊接工艺、改善焊缝性能等实际生产提供理论依据。
The paper simulated and analyzed the residual stress of weld aluminum on dissimilar metal weld joint of steel and copper by using ANSYS,and obtained factors affecting the welding residual stress.In addition,several comparison tests were conducted to analyze the in？ uence of plate thickness,weld seam and convection coeff icient on the residual stress.The results showed that the welding stress f ield was simulated accurately in a certain range by using ANSYS,which had some references for studying the welding process,constituting reasonable welding process and improving the welding performance.
