FATIGUE ANALYSIS OF RAILROAD FREIGHT CAR TRUCK BOLSTER

Fatigue analysis of a railroad freight car truck bolster was performed. The method of analysis incorporated finite-element static stress analysis, rainflow counting technique and cumulative damage theory. Design improvements were brought about through deformation analysis and the final design reanalyzed with the fatigue process.
