ABSTRACT: The equivalent stress at key positions of
Bogie Frame for DMUs Exported to Tunisia is obtained by using simulation
analysis. The evaluation of static strength and fatigue strength is checked
referring to UIC specification and Goodman sketch for welding materials. In
addition, the modal analysis of the frame is made, and the vibrational modal of
frame in given frequency domain is predetermined to evaluate the dynamical
behavior of the frame in order to meet the dynamical design requirements. The
results show that the key points of the calculated frame of the equivalent
stress are less than allowable stress, and thus it could provide a theoretical
foundation for the optimized design of frame structure and safety of industrial
production.
