Electromagnetic Field Analysis and Modeling of a Relative Position Detection Sensor for High Speed Maglev Trains
The long stator track for high speed maglev trains has a tooth-slot structure. The sensor obtains precise relative position information for the traction system by detecting the long stator tooth-slot structure based on nondestructive detection technology. The magnetic field modeling of the sensor is a typical three-dimensional (3-D) electromagnetic problem with complex boundary conditions, and ...
متن کاملStudy 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 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 کاملResearch on the Filtering Algorithm in Speed and Position Detection of Maglev Trains
This paper introduces in brief the traction system of a permanent magnet electrodynamic suspension (EDS) train. The synchronous traction mode based on long stators and track cable is described. A speed and position detection system is recommended. It is installed on board and is used as the feedback end. Restricted by the maglev train's structure, the permanent magnet electrodynamic suspension ...
متن کاملCFD Simulation of High-speed Trains: Train-induced Wind Conditions on Trackside Installations
Speed is the created air flow as well as slipstream effects as the trains move. These effects can have some level of impact on fuel and energy efficiency of the train, but their other important outcome is the emergence of turbulent flows at higher speeds which can cause aerodynamic drag forces followed by noise and vibration. Thus, slipstream effects have significant importanc...
