Fatigue cracks may occur at the weld toe or weld root in the fatigue control locations of the metro bogie frame, an effective fatigue assessment method is needed to analyze the bogie's fatigue reliability thoroughly. In this paper, the fatigue property tests of typical welded joints were completed, combined with the effective notch stress concentration factor, the effective notch stress S-N curve was determined. The effects of joint dimensions were studied to get a safer S-N curve which could be applied to the fatigue reliability analysis. This paper provides a theoretical and practical basis for the fatigue assessment of the metro bogie frame under service conditions.
