The Design of Bullet Train Process Bogie and the Finite Element Analysis of Frame Strength

Abstract. The process bogie is a special equipment for bullet train maintenance. Frame is the main the main load-bearing frame in the process bogie, and its fatigue strength directly affects the safety performance of the entire process bogie. According to the actual maintenance needs, the project design a process bogie. Using the finite element analysis software ANSYS, the finite element model of frame is established, and the frame strength and rigidity is analyzed. Referring to the "Bullet train bogie frame strength test method " (TB/T2368-2005) and the Ministry of Railways standard "Railway vehicles strength design and test standard " (TB/T1335-1996), the frame strength is assessed. The analysis results are consistent with the practical application
