In high-speed railways, adhesion between wheel and rail is a very important function to maintain safety and stable operation from the standpoint of braking and driving, in particular under wet conditions at the wheel/rail interface. This paper describes an experimental investigation, which mainly focused on the effects of surface roughness and water temperature on the adhesion between wheel and rail...
This paper describes the behavior of adhesion coefficient, i.e. the maximum traction coefficient in the rolling direction between rail and wheel under a water lubricated condition for various values of rolling speed, slip ratio, contact load, surface roughness and water temperature by means of a simplified theory. The adhesion coefficient has been analyzed here by combining the elasto-hydrodynamic...
