Geometric analysis of wheel-switch for new and old turnout

ByXu Zhang, Gang Shen, Dilai Chen

The worn wheel profiles of type LM and concrete symmetrical turnout section profiles are measured with instruments based on freight derailment accidents. The worn wheel profiles are compared with the standard wheel profile. The new and old turnout section profiles are compared for differences. The typical wheel profiles and two kinds of turnout section profiles are chosen to calculate wheel-switch contact points and contact stress to achieve differences and same points.
