New 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 کاملPantograph-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 کاملMultiple Pantograph Interaction with Catenaries in High-Speed Trains
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...
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...
متن کاملCatenary emulation for hardware-in-the-loop pantograph testing with a model predictive energy-conserving control algorithm
Pantograph current collectors, especially for high-speed trains, need to ensure safe contact with the catenary under stringent requirements on the dynamic contact force. A novel, high-dynamic pantograph test rig with accurate virtual catenary emulation is presented that allows for efficient, realistic, and reproducible testing. The complex dynamics of the pantograph/catenary interaction is mode...
