| Abstract: | How to reduce and control welding deformation is a major issue in the process of manufacturing the bogie frame of the high-speed locomotive. In this paper, based on the theory of the welding shrinking force, the finite element method is used to predict welding deformation of the bogie frame assembly as well as all the combination beams. According to the predicted deformation data, the pre-deformation magnitude and welding parameters are determined for design of the welding technology so that the minimum welding deformation and good welding quality can be guaranteed. Providing numerical reference for the new method presented in this paper is proved effective in reducing welding deformation and quality control of frame welding. |
