Experimental characterization of the vibration effects on wheels of a mass rapid transit vehicle

The aim of this paper is to present the results coming from an experimental campaign aimed at definition vibrations acting on a powered and trailer bogie railway vehicle for mass rapid transit during commercial service. results, multiple sensors placed in specific points two wheelsets, can give significative overview dynamic behaviour components, highlighting, when present, notable differences. available gave possibility justify correlate these differences characteristics bogies considered. study stresses presence peculiar cyclic solicitations that wheels wheelset undergo their A deeper investigation outcoming signals has been carried out keeping into consideration frequency content associated measurement system use. highlight wheelsets may experience significant high-frequency induced by gear pairs. implications findings represent argumentation discussion design requirements wheels.
