SOME BASIC STUDIES ON THE INFLUENCE OF SURFACE CONTAMINATION ON ADHESION FORCE BETWEEN WHEEL AND RAIL AT HIGHER SPEEDS

In order to investigate basically the influence of wheel/rail surface contamination on the adhesion force at higher speeds, traction force and slip ratio were measured with two types of rolling contact testing machines by taking a small amount of liquid paraffin as a contaminating model. And some theoretical analyses were done on the traction-slip relationship as well as the maximum traction coefficient, that is, the adhesion coefficient by taking account of the static and kinetic friction coefficients as well as contact rigidity.
