Co-Design Research on the Welding Structure of the Metro Bogie

Abstract:

In order to study the influence of welding process and local detail design to the life of the metro bogie frame, this paper, in view of the tee joint, researched the superposition of residual stress and external load influence on the structure strength by the finite element simulation to establish mechanical structure and welding process co-design method. Based on the above research, the fatigue strength of the overlapping structure of welding frame socket plate and beam was improved, by the co-design of the groove angle and joint-welding sequence.
