摘要：

The longitudinal - transversal vibration of a railway overhead contact system are considered. Special emphasis is placed on the analysis of dynamic behaviour of a catenary and pantograph for rail road cars moving at constant velocity. The dynamic state of the investigated system is described by a non-linear set of coupled partial differential equations with boundary conditions given by the ordinary differential equation. The damping properties of the interaction elements as well as dry friction between the string and the oscillator are taken into account. General results are illustrated by a numerical example in which the effect of the moving waves is noticeable.
