Abstract

This paper has investigated the strength of the bogie frame for the Korean tilting train that is being developed in KRRI. In this study, the loading conditions imposed on the bogie frame of tilting train were derived and the static and fatigue strength of the bogie frame has been evaluated. In order to achieve these goals, finite element analysis has been performed and the stress concentration areas were investigated. Based on the analytical results, the static load tests were conducted under the nontilting load conditions and the tilting load conditions. The test results were used to evaluate the fatigue strength of the bogie frame by Goodman diagram.
