Abstract

The running safety of the rolling stock depends on the design characteristics and the contact condition between wheel and railway. In this study, the effect of the conicity of wheel tread on the running safety is analyzed. The modal analysis results in $0.5\~0.6Hz$ natural frequency with lateral modes. However, the frequency analysis for the running simulation shows the frequency components near 1Hz. The running simulation shows that the KTX with GV40 wheel has less lateral vibration than that of XP55 as the KTX goes higher speed.
