Simulation-based estimation of wheel/rail friction coefficient and wear number considering results of full-scale roller-rig test

Simulation-based estimation of wheel/rail friction coefficient and wear number considering results of full-scale roller-rig test

When railway vehicles run on sharp curves, the coefficient of friction (COF) between the outer rail and the leading-outside wheel flange of a bogie is an important value related to problems such as wheel/rail severe wear, squeak noise arising from wheel/rail contact, and running safety against flang...
