Study of the wheel-rail adhesion under degraded conditions using a multi-axles roller-rig

ByN. Bosso, A. Gugliotta, N. Zampieri

The paper shows the development of innovative methodologies to simulate the adhesion recovery phenomenon by means of a scaled roller-rig. The test bench is composed of four wheelsets, which are in contact with the same couple of rollers. This layout allows to measure the adhesion coefficient recovery due to the cleaning effect produced by the wheelsets sliding.
