Abstract: | This study has assessed fatigue strength of bogie frame for Korean tilting train. For evaluation of the loading conditions, multi-body dynamic analyses have been carried out. And, strength analysis has been performed by finite element analyses. From these analyses, stress concentration areas were investigated. A total of 25 strain gauges were placed on these areas and static tests were performed. Based on the fatigue assessment, it was clear that the bogie frame satisfied structural safety. |
