abstract = {The goal of more energy efficiency requires lighter rail
vehicles and therefore lighter bogies. These bogies are
based on platforms to reduce design time and cost. For the
design of these platforms precise and safe design loads are
required that represent various operational conditions.
Therefore, the goal of this work is to develop a method to
determine standardised multi-body simulation scenarios for
bogie platforms. For this purpose, so called representative
synthetic scenarios are used due to their low simulation
effort compared to the simulation of real tracks. The
representative synthetic scenarios are created based on
operational statistics that represent a real track. The
scenarios consist of different horizontal elementary
scenarios. In this work, representative synthetic scenarios
were created and validated for the rail vehicle in use.
Vertical elementary scenarios were integrated into the
representative synthetic scenarios to also consider the
vertical track layout. The standardised scenarios summarize
real tracks. These tracks have not been measured with the
same vehicle. The measured motor torques, and braking forces
are therefore not automatically applicable to the vehicle in
use. Hence, synthetic motor torques, and brake forces were
created for the vehicle in use. The standardised scenarios
are designed to approximate target loads that were
previously defined based on various real tracks. To build
these scenarios, initial standardised scenarios were
created, simulated and compared with the target loads. If
the target loads could not be achieved, the operational
statistics were changed iteratively based on a sensitivity
analysis until the target loads were approximated with
sufficient accuracy. The sensitivity analysis ensured that
the statistics could be modified with fewer iterations.
Precise and safe design loads for rail vehicle bogie
platforms can be generated using the developed standardised
scenario generation method. This allows the bogie platforms
to be designed for a wide range of operational conditions,
while enabling a lightweight and energy efficient bogie
design.},
