    • Abstract
  • The numerical simulations have been done for both the conventional metal active-gas welding(MAG) and the dynamically controlled low stress no-distortion(DC-LSND) MAG welding,and the measurement has been done for the DCLSND experimental weldment as well,it is found that the simulating result is basically consistent with the measured data.Subsequently,the welding residual deformation of the partial side beam of bogie frame was selected as a research object,the optimization analysis of parameters of the heat sink had been done with the numerical simulation combining with optimization algorithm,and the alcording optimum scheme was obtained.The results showed that the control effect of welding residual deformation was obvious by the DC-LSND MAG welding with the optimum parameters.
