Simulation Research on Relieving Welding Residual Stress by Vibratory Stress Relief Technology

Abstract:

Analysis of the causes of welding residual stress and the mechanism of VSR, also give the sufficient condition of the exciting force. Firstly, use the thermal - structural coupling and cell life and death of the welding process simulation, get the welding residual stress. Consistent with the theory. Secondly, build the VSR simulation process based on the use of the harmonic response analysis and welding simulation. select the appropriate VSR process parameters through the simulation results. Finally, VSR process simulation, analysis showed that the peak of residual stress after VSR treatment decreased by about 33%, and achieved good results. The numerical simulation analysis provides a strong basis for rational selection of the parameters of the VSR.
