Effects of temperature and humidity on railhead friction levels
نویسندگان
چکیده
This paper explores the research gap involving links between railhead temperature, relative humidity, and coefficient of friction (adhesion level) at wheel/rail interface as found on track across UK. Existing work done in this field has mostly been carried out laboratories which limits variation environmental conditions. Weather data were collected from different sites England, generating a real representation Correlations established dataset to give greater insight into mechanisms low adhesion when can be expected take place. provide an avenue better predict occurrence interface, therefore improving safety within rail network. Results analysis showed that high humidity conditions, independent reduces level railhead. Showing occur warmer temperatures, such those typically experienced early autumn where there is humidity.
