Abstract

Weight reduction of the carbody is of great concern in developing high speed tilting train. Currently the composite materials are widely applied to the carbody structure due to their excellent material properties such as high specific strength and stiffness characteristics. In this paper, finite element analysis was conducted to design sandwich structures of composite carbody of the Korean Tilting Train eXpress(TTX). Several load tests on the carbody according to JIS E 7105, such as static vertical, compressive and torsional load tests was performed by finite element analysis, and the structural safety of composite carbody structure was verified.
