Multiple Pantograph Interaction with Catenaries in High-Speed Trains
نویسنده
چکیده
This work presents a fully three-dimensional methodology for the computational analysis of the interaction between catenary and pantographs. The finite element method is used to support the modeling of the catenary while a multibody dynamics methodology is applied to support the pantograph modeling. The contact between the two subsystems is described using a penalty contact formulation. An high-speed co-simulation procedure to ensure the communication between the two methodologies is proposed. The application of the proposed methodology to the study of the interaction of multiple pantographs of a train with a catenary demonstrates the influence of the leading pantograph over the quality of contact of the rear pantograph.

Pantograph-Catenary System Modeling Using MATLAB-Simulink Algorithms
Contacts between pantograph and catenary are the most critical parts in the transmission of electrical energy for modern high-speed trains. Contact wire oscillations change combined force between pantograph and catenary, and the contact may even get lost. Therefore special pantographs and catenaries have been developed and further constructive changes are under development. A design criterion i...
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 کاملNew Designing Procedure for Pantograph of High-Speed Trains
In Japan, several projects to increase train speed are underway, requiring a new generation pantograph that achieves further reduction in aerodynamic noise. However, as reduction of pantograph noise usually conflicts with the stabilization of its lift force characteristics, a number of experiments have to be conducted to develop a new type of pantograph. The aeroacoustic and lift force characte...

متن کاملDynamics and Control of a High Speed Train Pantograph System
High speed trains permit faster travelling between long distance destinations, making it an easy and comfortable way of travelling. The pantograph is the element of the train that collects electrical current from the cable system above (the catenary), to the train motors. The contact force variation can cause contact losses, electric arc formations and sparking. This deteriorates the quality of...
