焊接顺序对残余应力和变形影响的数值模拟
Numerical Simulation on Effects of Welding Sequence on Residual Stress and Deformation of Multi-pass Welding
摘要
Abstract
A finite element model of the 12 mm thick multi-layer and butt-welding was created by finite element software.The residual stress and deformation were simulated under two welding sequence.The results show that the welding sequence of alternating positive and negative directions can effectively reduce the residual stress after welding,but has little effect on the welding deformation.And a viable dynamic simulation analysis method of three-dimensional stress and displacement field was obtained in multi-layer butt-welding of mid-thick plates.关键词
