Electromagnetic track brakes in commuter and main-line trains work independently of the wheel-rail contact. Therefore, they play an important role especially in low adhesion conditions. Today’s demands on braking performance require that track brakes stay active until the train comes to a full stop. Measurements during field tests have shown that under these conditions severe self-excited vibrations may occur. In order to analyse these vibrations, a coupled electromagnetic and mechanical model is developed. From this model, two different mechanisms have been identified that may lead to self-excitation. Results show how design parameters may be used to reduce or mitigate self-excited vibrations that may damage the structure or increase stopping distance.
