Study on Braking Panels in High Speed Trains Using CFD
With speed increasing in high-speed trains, due to limitations of other types of brakes, aerodynamic brake has become an important braking method. In this task to make better use of brake’s panel different configurations are examined and the best panel shape which provides the reasonable drag coefficient is introduced. The results of simulations are carried out with the computational fluid dyna...
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 کاملEurostar e320 high-speed trains
In December 2010, Eurostar International Ltd. awarded Siemens a contract for ten interoperable 16-car highspeed trains. These trains are based on Velaro®, the world’s most highly diversified high-speed platform. Starting in 2014, these trains will be added to the existing Eurostar fleet operating on the London–Paris–Brussels line running through the Eurotunnel between Great Britain and the Euro...

متن کاملSustainability Aspects of Energy Conversion in Modern High-Speed Trains with Traction Induction Motors
Some aspects are illustrated of energy conversion processes during the operation of electric railway vehicles with traction induction motors, in order to support transport systems’ sustainability. Increasing efforts are being expended to enhance the sustainability of transportation technologies and systems. Since electric drive systems are used with variable voltage variable frequency (VVVF) in...
