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 eliminate torsional oscillations of wheelsets. Therefore, a simulation wheelset drive model including a detailed model of the asynchronous traction motor control was built. The results of computer simulations show that the torsional oscillations can be effectively eliminated by avoiding the resonance states between the excitation frequencies given by pulse width modulation of the inverter and the eigenfrequencies of the mechanical part of the drive. Furthermore, it was found that the presence of torsional oscillations of the wheels can be detected based on the traction motor current ripple. The wheelset drive model was subsequently implemented in a simulation model of a four-axle locomotive. A new algorithm of an anti-slip protection system that utilizes motor currents was implemented in the model. Simulations show that such an anti-slip protection system can prevent the occurrence of undesired large amplitude of wheelset torsional oscillations. The models and simulation results are presented in detail in the paper.

Abstract. In high-speed train, the harmonics generated in invertor due to control and nonlinear of switch may lead to the torque ripple in different frequency and amplitude. The driving device which consists of rotor, coupling, gear, shift and wheels of bogie has some resonance frequencies. When there are frequencies which are same or close to the resonance frequency of shifts in the torque pulsation, the shifts would be vibrated. First the paper analyzes the cause and influence of the torque pulsation. Then the author calculates the vibration frequencies of drive devices. Finally the author simulates the coupling system of driving motor and bogie driving device.

“…In the other hand, the more considered mechanical parts are rails and wheels, vehicle and bearings of bogie in the proposed monitoring methods [9]- [20]. An overview of maintenance and reliability of European traction systems has shown that the electrical part including inverter becomes less faulty than the mechanical parts [21].…”

The AC electrical machines have been used in railway traction systems for about 40 years ago. The main advantage of this choice is to discard the power limitation and permits high power light-weight drives. This enable constructor to achieve higher traction speed and this area now is in permanent development. In this way, the security and reliability of the system becomes more important. The railway traction has a complex structure and the diagnosis of the electromechanical system based on non invasive electrical sensors becomes the interest of research in recent years. In this paper, a test-bed based on a real traction bogie is proposed to study machine current signature analysis for mechanical condition monitoring.
