Strength Analysis and Reserch on Bogie Frame of AC Transmission Heavy Rail Car

Abstract：To study the strength of the bogie frame of AC transmission heavy rail car， finite element method was applied to analyze the strength of the frame under the operating conditions of the bogie of the electric drive heavy rail motor car. The upper cover plate structure was optimized based on the calculation results， and static strength and modal analysis was performed again. The results showed that the relevant standards and application requirements were met.

Keywords：rail car; bogie frame; strength analysis; fatigue analysis; modal analysis
