| 摘 要： | 在高频焊管生产过程中,消除因高频焊接造成的焊管残余应力是一项重要的工序,预先得出焊管残余应力场对于消除焊管残余应力具有指导意义.利用ANSYS参数化语言APDL,建立高频焊管的有限元模型,采用高频焊接线热源模型进行计算,同时考虑高频焊管有限元模型的热边界条件及物理结构约束,从而获得高频焊管在焊接过程中三维应力场及位移场...

| Abstract: | In the production process of high-frequency welded pipe,the elimination of the high-frequency welding residual stresses caused by high-frequency welding is an important working operation.A knowledge of the residual stress of the welded pipe in advance of welding is significant for the residual stress elimination.Making use of APDL language embedded in ANSYS,a finite element model of high-frequency welded pipe was established.Then the linear thermal source model was used to conduct the computation.Meantime,t... |
