In recent years, railway carbodies have become more and more lighter, raising concerns about potential deterioration in ride comfort due to reduced structural stiffness. Most previous studies on railway vehicle dynamics have simplified either the dynamics of traction devices or their influence on carbody elastic vibrations. However, for driving vehicles, there has been little investigation into how the dynamic behavior of driving bogies during traction affects the elastic vibrations of carbody. To address this gap, this study develops a planar driving elastic carbody vehicle model based on multibody dynamics theory. Using this model, we examine how the behavior of driving bogies under re-adhesion control influences the flexural vibration of the elastic carbody.
