Railways

The development of modern railway systems such as trams, high-speed or city trains is a challenging task. Engineers have to consider the dynamic dimensioning of driveline components, dynamic behavior examination, component integration and matching as well as effects on wheel-to-rail traction.

How can innovative transport systems be designed in the face of mounting requirements? How can real operating conditions be simulated combining different interacting physical domains such as mechanics, hydraulics and pneumatics?

Thanks to ITI’s simulation products, engineers and scientists are able to develop reliable railway systems – from concept through to testing. The intuitive 1D to 3D software platform SimulationX ensures a consistent physical approach when modeling, simulating and analyzing modern railway systems.

Fields of application

OEMs and suppliers model and analyze components, validate design choices and swap system models early on in the design cycle. SimulationX supports them with excellent performance and facilitates quick analyses and reliable evaluation of dynamic system behavior.

• Development of any drivelines (electric, diesel-electric, diesel-hydraulic), any bogies, HVAC, cooling systems, locomotives, high-speed/intercity/regional trains as well as rail control solutions

• Setting up multi-body system models for locomotives

• Controller design and testing

• Modeling anti-slip and traction control including influence of sensors and sampling

• Friction modeling for power transmission from wheel to rail

• Examination and evaluation of critical load scenarios, such as starting/braking, effect of passing rail joints, changing contact situations (dry and wet rails), synchronization failures and short circuits (2 or 3 pole) in drive motors

• Assessing the performance of hardware before an actual implementation using real-time models

• Component integration and matching in drivelines

• C-Code export, co-simulation or integration of external control codes

• Transverse drive sets for electric rail vehicles
