Summary

One method to evaluate the running stability of a railway vehicle is the running test on roller rigs. In this paper, running tests were carried out by means of a frequency response test with lateral forced excitations in order to investigate the effect of a vehicle model on the dynamic behaviour of the vehicle. As a result, it was verified that the lateral dynamic behaviour of a car-body in a full-body vehicle model and a load frame in a half-vehicle model is a vibration mode in which lateral, yawing and roll rotation are coupled. Further, the coupling of the yawing is more apparent in a half-vehicle model. In addition, the position of the centre of the roll rotation movement of the body is influenced by the height of the coupler or joint that fixes the body to the ground.
