Query: Symbolic Multibody Methods for Real-Time Simulation of Railway Vehicles   In this work, recently developed state-of-the-art symbolic multibody methods
are tested to accurately model a complex railway vehicle. The model is
generated using a symbolic implementation of the principle of the virtual
power. Creep forces are modeled using a direct symbolic implementation of the
standard linear Kalker model. No simplifications, as base parameter reduction,
partial-linearization or look-up tables for contact kinematics, are used. An
Implicit-Explicit integration scheme is proposed to efficiently deal with the
stiff creep dynamics. Hard real-time performance is achieved: the CPU time
required for a very stable 1 ms integration time step is 256 {\mu}s.
