摘要

In the present work,the JCOE forming is investigated using the finite element (FE) method.A twodimensional FE model is established for the plane strain condition by FE code ABAQUS,and the FE model is validated by experiments.The aim of this research is to investigate forming quality states in the JCOE forming process;in particular,the effects of technological parameters on forming quality are evaluated.Taking the JCOE forming process of X80 steel Φ1 219 mm × 22 mm× 12 000 mmwelding pipe for instance,the deformation characteristics of JCOE forming are analyzed,in which the geometry of the formed pipe,residual stress distributions and effects of process parameters on JCOE forming quality can be obtained.Thus,the presented results of this research provide an effective approach to improve welding pipe forming quality.
