Static and Fatigue Analysis of Bogie Rotating Frame for Light Rail Train

Rotating bogie frame will be used in the bogie for the Light Rail Train being developed. In development of the bogie, analyzed were the structural strength and fatigue characteristics of the rotating bogie frame. Defined load cases were applied for the analysis. No part of the rotating bogie frame is subjected to stress beyond the fatigue endurance limits of the material used when grinding the weldment of the lower plate link bend. It is concluded that the rotating bogie frame is considered safe in the view of the structural strength.
