ON WHEEL-RAIL ADHESION. DIMENSIONAL CONSIDERATIONS FOR TESTS WITH MODELS

SULL'ADERENZA RUOTAROTAIA CONSIDERAZIONI DIMENSIONALI PER ESPERIENZE SU MODELLI

After recalling the main notions of the wheel-rail adhesion phenomenon and establishing a rational working dependence between the adhesion coefficient and a series of characteristic undimensioned groups, the author defines the appropriate similitude criteria enabling the phenomenon in question to be reproduced on the model. Finally, consideration is given to the possibility of carrying out research with the model which would not only be useful in throwing light by experimental means on several important interactions between vehicle and track, but also because such research could quickly lead to the development of practical and economical methods for full-scale applications.
