Analysis of the Influence of Superelevation of Subway Line Act on Wheel-Rail Wear

Abstract:

In order to reduce the wheel-rail wear and improve the safety and comfort of the vehicle during the running round the curve section, in this paper, based on the theory of vehicle dynamics and by the dynamics software-SIMPACK, it created a model on the relationship of wheel-rail. It conducted research on the three situation include deficient superelevation, normal superelecation and surplus superelevation when the train crossing the curves. It analysed the change regulation about the two parameters which are rate of wheel load reduction and overturning coefficient during running of the train. Most importantly, it analysed deeply about the regulation of the change about wear power and wear number accompanied by the change of superelevation. Two main conclusions were made in this paper. The first one is wear number and the changes of superelevation are negatively correlated. The second one is wear power and it is positively correlated. It suggested us that it should be in lower when the train crossing the curves. It should use lower deficient superelevation when it can’t in the case of the best situation.
