Abstract
AbstractBased on the fundamentals of tractive rolling contact mechanics, a method is described which is suited for calculating traction coefficients. Both the deformation and the adhesion component of friction are taken into consideration. It is demonstrated that the maximum traction coefficient is not a constant, but takes different values under various load conditions as a result of changes in the micro‐geometrical pattern. Using the load‐specific maximum traction coefficient it is possible to predict a fairly accurate value of the traction coefficient of the tractive rolling contact.In addition, the results of wear investigations are reported, and an approach to apply test results to the real wheel/rail system is described. The tests were carried out with materials common in railway design; in particular, R7 wheel material and standard‐grade 900A rail material were used. During the tests the normal force and the creep were varied. Wear investigations conducted on the test machine revealed that the relationship between friction work and wear volume is an almost linear function.
