焊接变形对10Ni3CrMoV接头疲劳失效行为的影响
Influence of Welding Deformation on Fatigue Failure Behavior of 10Ni3CrMoV Joint
摘要
Abstract
In order to investigate the effect of bending deformation on the fatigue life of welded joint of 10Ni3CrMoV plate,finite element simulation software Ansys Workbench and fatigue analysis software Ansys nCode Design Life were used to establish a welded joint specimen model based on the actual shape and size of the welded joint,and its fatigue life was simulated and calculated.The results indicate that the bending degree is a critical factor influencing the fatigue life of welded joints.Stress and strain concentration mainly occur at the weld toe of the welded joint,and variations in the bending degree can alter the fracture location of the specimen.By optimizing the welding sequence and incorporating an arc plate,deformation can be effectively controlled,and the fatigue performance of the joint can be enhanced.关键词
