Study about Improving Method of Curving Performance with Friction Control Between Wheel/Rail (Effect of Spraying the Friction Modifier on the Inner/Outer Rail at the Curve Section)

The concept of controlling car dynamics with the parameter of creep force by using friction modifier was proposed by the authors. The fundamental experiment of evaluating creep force characteristics with or without friction modifier by the two-roller-rig testing machine was performed. On the other, on-board spraying friction modifier system has been developed and equipped with the service car showing the effect of improved carving performance. This paper presents experimental and theoretical results of improved curving performance by the proposed method of friction modification between wheel and rail with scaled model vehicle.
