摘要
采用大型非线性有限元软件Marc对ERW直缝焊管的排辊成型过程进行了模拟,获得了管坯各截面形状和管坯应变场分布。分析了带材成型过程中的变形情况与试验的对比以及应变的分布规律,为ERW焊管机组的孔型设计及排辊调整提供理论依据。
The cage roll forming process of ERW straight-welded pipes is quite complicated,which is simulated by means of a large-scale and nonlinear finite-element analysis software Marc.The sharp of the pipe about every cross section and strain fields were got.The laws of strain distribution and the forming status contrast between the simulation and the experiment in the pipe forming process were analysed,which could provide reference for the pass designing and set-up of Straight Welded-Pipe Mill.
