Ground Vibration Induced by Railway Traffic – The Influence of Vehicle Parameters

Measurements of ground vibration induced by a two-car EMU railway vehicle have been made at speeds up to 250 km/h. The results show an increasing ground vibration level with increasing speed and a clear excitation generated by each passing wheelset and the discrete sleeper support. Simulations with a multibody vehicle model on a railway track, including a ground model consisting of isotropic elastic layers, show good agreement with the measurement results.
