摘要
Abstract
Vacuum electron beam welding has been widely used in the production of thick and large structures,and the weld-ing distortion problem of thick and large structures is of great concern.In this study,the SUS304 stainless steel I-beam struc-ture with a web thickness of 40 mm,and flange thicknesses of 54 mm and 47 mm as the research object,and vacuum elec-tron beam welding was used to weld the flange and web of the I-beam structure.The deformation of the structure after weld-ing was measured by the MetraSCAN 3D scanner.Based on the measurement results,the influence of structural restraint on the welding distortion of thick and large structures was examined.At the same time,a"thermo-elastic-plastic finite element method"with enhanced length moving heat source model was developed based on MSC.Marc software to simulate tempera-ture field and welding distortion.The comparison between the simulation results and experimental measurements shows that the heat source model with enhanced length can calculate the welding distortion of thick and large I-beam structure with a high precision,and the overall consistency is up to 90%.In addition,both the numerical simulation and the measured data suggest that the structural restraint method can effectively control welding deformation.关键词
