Vehicle Dynamics and Train-Induced Ground Vibration—Theoretical Analyses and Simultaneous Vehicle, Track, and Soil Measurements

Ground vibrations near railway lines are generated by the forces that acting between wheel and rail. It seems to be a straight forward assumption vehicle dynamics important for level frequencies of excitation forces. Different phenomena analysed their role in ground vibrations: rigid body modes bogies, elastic (bending) car body, wheelset. The theoretical analyses use models, simplified detailed models. Some these problems vehicle–track interaction where 3D finite-element boundary-element models have been used track soil. is shown or flexible well frequency range (4 100 Hz). They an influence on force but additional rather small can neglected vibration prediction. results checked experimental simultaneous measurement vehicle, track, vibrations.
