Abstract

Railway vehicles have to undergo extensive authorization tests before
they are put into service. This is especially true for railway vehicle brake systems,
as these tests are very costly, extensive, and time-consuming. Virtual testing
is assumed to represent a feasible solution to decrease these efforts. The use of
simulation methodologies requires a technically accepted process, a credible and
trusted model, calibration of this model, and a minimum of available measurement
data. The challenge is to guarantee the exactly same safety levels that are
achieved through real testing, and to provide a convincing argument, why simulation
methodologies are suitable for that purpose. In our contribution, we highlight
the results of the European Shift2Rail PIVOT-2 project, contributing to these
challenges. Our approach integrates into existing railway vehicle development processes.
Existing measurement data is selected to calibrate and validate the model.
This allows for virtual testing as a novel tool, to be applied before or during vehicle
development. The presented approach is under discussion with important bodies
like the European Railway Agency (ERA) and NB-RAIL. Furthermore, the approach
is also based on existing standards that already recommend the application
of simulation methodologies, e.g., standards regarding methods for calculation of
stopping and slowing distances (EN 14531) or wheel slide protection (EN15595).
Many methods, tools and processes of the railway industry are currently pushed by
increasing levels of digitization. The application of simulation technologies in the
railway sector is also driven by ongoing standardization activities of international
consortia. In the end it is expected that these innovations will lead to a more competitive
railway engineering market, including more software tool vendors and
service providers, striving for higher quality railway vehicles and products. It is
expected that these innovations contribute to a decreased time-to-market, putting
new vehicles faster into service, to ultimately contribute to sustainability goals,
like reduction of emissions in transportation.
