The Individual Drive of a Wheelset and the Problematics of Its Electromechanical Phenomena

Vehicles
This paper deals with the phenomenon of torsion oscillations in railway vehicle drive systems. The main goal is to reduce the risk of presence of torsional oscillations in wheelset drive, eventually to propose systems to effectively identify and ...
