Stick-Slip Movement in Driving Axles of Railway Vehicles equipped with Damping Devices

Abstract

In this article, we carried out a study on the behaviour and efficiency of an oscillation-damping system, mounted on the driving axles of railway vehicles to mitigate stick-slip oscillations. The occurrence of the stick-slip phenomenon is particularly harmful in operation because it generates wear on the tread surfaces of the wheels and rails, generates fatigue stresses in the axles and diminishes locomotive performance. To reduce these inconveniences, we proposed installing on the axles a damping system to reduce stick-slip oscillations and studied the behaviour and the efficiency in the operation of this system.
