Numerical Simulation and Deformation Analysis of Single-pass Multi-layer Stress Field in Arc Additive Manufacturing

  • 摘要: 利用Simufact Welding有限元分析软件,采用生死单元法对镍基高温合金GH4169钨极惰性气体(TIG)保护焊电弧增材单道多层应力场进行数值模拟。采用盲孔法测试选取的基板上垂直于焊缝中垂线上各点残余应力,得到实测值与模拟值误差在10 MPa内,误差百分比约为2.8%。对增材工件进行变形分析,结果表明:重复热循环作用使得成形件内应力不断骤升骤降,且应力峰值逐层递减。成形卸载后,残余应力主要集中于成形件起弧与熄弧处底端。成形件冷却至室温后总变形量呈对称分布且在横向方向上翘曲程度最大,总变形量达到1.82 mm。
