Summary

In the majority of papers devoted to the dynamics of structures subject to a moving force, various types of kinematic excited oscillations are studied. The theory applied to high-speed trains running on the classical or refined tracks seems to be very simplified. This investigation is supplemented by modern travelling wave approaches proposed for the dynamic analysis of the wheel-rail system. In this case the velocity of the contact point motion is a crucial problem. The phenomena discussed in this paper can be used for the estimation of the contact point speed allowing an effective contact forces analysis.
