Rolling resistance

Determining rolling resistance values in order to adjust the traction power of a new railway vehicle and/or infrastructure.

Objectives

Determine the factors increasing the resistance to forward movement of a vehicle (rolling resistance and aerodynamic drag) by measuring several parameters: Axle speed, acceleration, forces, traction current and wind speed
