Variation in driving or braking force can cause longitudinal vibrations of the vehicle, which sometimes causes a fall in adhesion and further slipping and skidding. As such, it is essential to elucidate the relationship between tractive force and longitudinal vibration in consideration of electric and mechanical systems. Understanding this relationship can facilitate improvement of motor control methods. This paper reports on investigations into longitudinal acceleration produced by variation in tractive force, and on results of a comparison between test results using an actual train set and results obtained from numerical simulation.
