| Abstract: | This paper makes a study of the influence of shot peening on welding deformation of heavy transport vehicle frame longitudinal beam,uses MSF-3M stress analysis instrument to measure the residual stress of welding workpieces and measures the deformation of the welded and unwelded workpieces using the 3D-coordinate measuring instrument and then draws the 3D graphics of workpieces by the use of Matlab software.The deformation is analyzed through the standard deviation of its deformation data.It is proved that the welding deformation of the heavy transport vehicle frame longitudinal beam can be improved and controled effectively by shot peening. |
| Keywords: | heavy transport vehicle frame shot peening welding deformation |
