摘　　要：针对高速动车组转向架管类工件焊接过程中存在的残余应力问题,借助先进的数值仿真技术和手段,研究不同焊接顺序条件下焊接残余应力的分布规律,通过对计算数据的充分分析,对确定合理的工装以及焊接变形控制方法提供理论和数据支撑依据,为构架结构优化设计、焊接工艺设计提供有力支持。Aiming at the residual stress in the welding process for bogie of the higb speed EMU,the distribution law of the welding residual stress under different welding sequence conditions is studied by means of advanced numerical simulation techniques and means. The adequately analyzed data provides strong support for determining the reasonable tooling form and the deformation control method,and for the structural optimization design and the welding process design.
