TLDR
In this paper, a beam model was used to model the adhesion characteristics after saturation of adhesion force between the wheel and rail in a wet condition for wheel slip prevention control for railway vehicles.Abstract:
In order to enhance the speed of wheel slip prevention control for railway vehicles, modeling of adhesion characteristics after saturation of adhesion force, which had hitherto not been performed with trains, was performed via a beam model. The behavior of adhesive force between the wheel and rail in a wet condition was examined with a brake performance test stand for an actual vehicle. Results of comparing the model and test values indicated that the beam model represented test values well.read more

Control system for maximum use of adhesive forces of a railway vehicle in a tractive mode
TL;DR: In this paper, an adhesion control system of railway vehicles based on an observer, which allows one to determine the maximum tractive torque based on the optimal adhesive force between the wheels (wheel pair) of a railway vehicle and rails (rail track) depending on weight load from a wheel to a rail, friction conditions in the contact zone, a lateral displacement of wheel set and wheel sleep.
