A Three-Dimensional Calculation for Dynamic Pantograph-Catenary Interaction
Dynamic pantograph-catenary interaction is one of the most critical aspects to consider in catenary design, especially in high-speed rails. It is essential to maintain a constant power transmission in order to achieve high speeds and avoid the production of electric arcs, which damage the wires. This paper shows a tool, called InDiCa 3D, based on a three-dimensional model to solve the dynamic p...
متن کاملSimulating the dynamic interaction between pantograph and catenary
This article presents the simulation environment developed and used by Deutsche Bahn AG in order to simulate the dynamic interaction between pantograph and overhead line system. The program has been developed in co-operation with Heinz-Nixdorf-Institute of the university of Paderborn, Germany. Much importance was attached in the realistic modelling of the system’s behaviour when developing the ...
متن کاملNon-destructive analysis (NDT) of pantograph and catenary interaction
In the last decades the development of very high speed trains in railway transportation requires new maintenance strategies. New trolleys equipped with innovative measuring systems have been employed for monitoring overhead lines (catenaries). Using this system gives two great advantages: i) the diagnose can be performed with a low level of breaking in railway traffic; ii) the monitoring can be...
متن کاملModeling of Pantograph-Catenary dynamic stability
The purpose of this paper is to describe the possibilities of studying the influence of forces external variables on the stability of motion of dynamical systems modeled by systems of differential equations with periodic coefficients of stability. The method is applied to analyze the influence of external harmonic forces on the stability of motion of the pantograph couple contact wire electric ...
متن کاملPantograph-catenary Dynamic Interaction for a Overhead Line Supported by Noise Barrier
Subject of the paper is a particular configuration of overhead line, in which noise barrier structure is used as supports of the catenary instead of standard poles. This configuration is foreseen in case the noise barrier position is in conflict with the poles location. If the catenary is supported by the noise barrier, the motion that the latter undergo due to wave pressure associated to train...
