Structural Assessment for Bogie Frame of 180km/h Korean Tilting Train

Abstract:

This paper has performed the fatigue strength evaluation for the bogie frame of Korean tilting train. In order to verify the structural safety of the bogie frame, we firstly investigated the loading condition imposed on the bogie frame. The bogie frame of the tilting train is exposed to the more severe loadings compared with the conventional one because of the tilting of the carbody and the high-speed curve negotiation. We have conducted some multi-body dynamic analyses to extract the load condition by tilting on curve. The finite element analysis is used to obtain the stress distribution. Through this study, we could make sure the safety of the tilting bogie frame.
