The simulation of pantograph and catenary: a PDAE approach
Recently, the coupled dynamical simulation of pantograph and catenary in high speed trains has found much interest. The equations of motion form a partial diierential-algebraic equation (PDAE) that combines a partial diierential equation (PDE) for the catenary and a diierential-algebraic equation (DAE) for the pantograph. In the present paper we discuss the relation of this PDAE model to curren...
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 کاملOn Modelling and Control of Pantograph Catenary Systems
The paper describes modelling and control techniques studied and applied to selected pantograph-catenary (PAC) systems. The work has been co-funded by the European Union under the ERDF project: PAntograph-Catenary Interaction Framework for Intelligent Control (PACIFIC). Mechanical models of PAC systems are implemented in MATLAB using novel techniques, where applicable. Next, important physical ...
متن کاملHigh-speed railway pantograph and catenary dynamic simulation system modelling and verification
The dynamic simulation system of a pantograph and a catenary has been built by using the finite element method, in which the pantograph is equivalent to a threemass-damper-stiffness system and the catenary contains only cable and beam elements. Considering droppers as nonlinear elements only stressed by tension, a sliding contact model of the pantograph and catenary is coupled by penalty functi...
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 ...
