According to the standards of UIC615-4, EN13749 and ERRI B12/RP60, direct-drive permanent-magnet bogie flexible frame loads in exceptional and service load cases were calculated. Static and fatigue strength was analyzed based on FEA software, then fatigue strength was evaluated by Haigh diagram. First six order modal analysis of the flexible frame was conducted, so as to check the mode of vibration and stiffness characteristic. The result showed that the flexible frame meet the static and fatigue strength requirements from the related standards.
