Performance of wheel/rail lubricant with Axle Rolling Machine

Abstract

The wheel-rail contact adhesion condition can cause various problems including rail wear vibration and noise slipping and overrunning Lubrication between the wheel and rail can reduce or prevent these accidents This study will discuss various lubricants and wheel-rail lubrication condition through experiments as well as the cost problem caused by excessive lubricant consumption in the underground section of the TRA Kaohsiung line and discuss the influence of lubricant consumption and water substitution The axle rolling machine combined with the incremental encoder can obtain the speed between the wheel and the rail the nominal adhesion coefficient and the creep rate When the amount of lubricant is different the lubrication distance is longer when the amount of lubricant is more than that of less and its effect is significant Tests have found that water and lubricants change their performance with changes in water volume When the amount of water is small it will mix with lubricant to increase the lubrication distance When the amount of water increases the lubrication distance will be shortened due to the cleaning of the lubricant
