Rail Systems: Rolling Stock & Infrastructure

VIRTUAL VEHICLE drives the railway industry forward.

We provide collaborative research on railway technologies by seamlessly integrating virtual prototypes, information extraction, scientific methods, tools and processes on each level of the railway system.

 

Our partners benefit from the development of established simulation methods and digital tools. We combine know-how on model-based and data-driven approaches, optimising vehicle and infrastructure components. Depending on the scientific question or target component, suitable model-based and data-driven methods are combined and validated in a hybrid approach to achieve the best informative value.

 

Via developing and using digital technologies, methodologies and tools, we can optimise the behaviour of rail systems, improve vehicle dynamics, and enhance the overall passenger experience. In Rail Systems, VIRTUAL VEHICLE acts at the whole system level.

We think beyond 2040 at system level

  • Shorten innovation cycles through digitalization
  • Drive forward research for implementation
  • Maximize reliability of the rail system through intelligent and reliable algorithms
  • To contribute to a single European railroad area

Green Digital Mobility

Rail Systems – Backbone of Green Digital Mobility

At VIRTUAL VEHICLE, our research contributes to a further optimisation of the European rail system via improved understanding of vehicle-track-interaction and vehicle dynamics phenomena. As a result, we aid to maximize the reliability of the rail system through intelligent and reliable algorithms and contribute to the goal of doubling the capacity. Furthermore we positively influenced a faster market uptake, taking virtual validation methods and life cycle costs into account.

 

In addition to our core expertise, topics such as sensor technology and electrification, ATO, human factors research, and systems for the end-to-end networking of component and process data are becoming increasingly important.

Green Digital Mobility

Vehicle-Track-Interaction

Effective Vehicle-Track-Interaction is crucial for safe and efficient railway operations.

 

We focus our fundamental research on deterioration phenomena of vehicle and track components. Moreover, our simulation solutions enable decisions on optimised materials, life cycles, and maintenance plans.
