Virtual Fatigue Experiment Analysis of Welded Bogie Frame
Fatigue failure easily occurs in the weld seam of bogie frame, fatigue life prediction is very important. Based on the UIC615-4 (Motive power units- Bogies and running gear-Bogie frame structure strength tests) and IIW standard (Recommendations for fatigue design standard of welded joints and components-IIW document XIII-1965-03/ XV-1127-03), fatigue test process of bogie frame is simulated by means of finite element method. Using Miner cumulative damage theory, on the basis of IIW welded joints S-N data, fatigue life of the welded frame is predicted, and the virtual fatigue test of welded frame is completed. During the phase of product design, virtual fatigue test technology can be used to evaluate the fatigue strength, which can find the weak part and improve product design quality.
