The DLR RailwayDynamics Library: the Crosswind Stability Problem

High crosswinds affect the stability of railway vehicles, in 
particular if they run on very high speed to reduce traveling 
time, if they are configured as double-deck cars to increase 
the number of passenger seats and if they use lightweight 
design in order to reduce life-cycle costs. This 
is why crosswind stability is an active field of research 
within the project Next Generation Train. However, this 
field relies on the cooperation of two different domains, 
namely aerodynamics and vehicle dynamics. With this 
background a crosswind stability tool was implemented in 
Modelica as a part of the DLR RailwayDynamics Library. 
This tool gathers data from scaled wind tunnel measurements 
and multibody data on the railway vehicle in order 
to rapidly analyze and assess the risk of overturning due 
to high crosswinds. To a large extent the tool is oriented 
towards the associated homologation rules and standards. 
However, the tool is as well supposed to support future 
advancements of these standards by providing capabilities 
for the stochastic analysis of the crosswind stability problem.
