Controlling the friction between wheel and rail is direct and very effective measures to Improve the curving performances of railway trucks, because the curving performances depend much on friction characteristics Authors have proposed a method, "fllction control", which utilizes friction modifier (KELTRACKTM HPF) with onboard spraying system With the method, not only friction coefficient, but also fuction characteristics can be controlled as expected In this study, MBD simulation is very valuable tool to foresee the effect of the contiol In advance of experiment With real car And the creep characteristics of wheel/rail contact With the friction modifier takes very Important role In the simulation In this paper, authors propose a theoretical model of wheel/rat I contact condition considering the creep characteristics of friction modifier, Which is derived the application of principle tribological theories<br/>
