Description
Summary:The problem of improving the quality of the current collection process becomes particularly relevant at the high speeds of rolling stock movement. First of all, the quality of current collection is related to the interaction of the pantograph current collector with the contact wire. From the point of view of mechanics this is the process of the interaction of two oscillatory systems with a randomly varying degree of interaction. The analytical consideration of the dynamics of such interaction in the best case (if it is feasible at all) can only lead to probabilistic estimates of quantities interesting from the practical point of view. It was the motivating reason to develop some classes of the models of the reaction of the contact wire to the static and dynamic effects of the pantograph. We found the natural oscillation frequencies of the catenary and their corresponding eigen functions taking into account the structural elements providing an equilasticity of the catenary.
