Abstract
EN: This paper is an outcome of an international collaborative research initiative.
Researchers from 24 institutions across 12 countries were invited to
discuss the state-of-the-art in railway train air brake modelling with an
emphasis on freight rains. Discussed models are classified as empirical,
fluid dynamics and fluid-empirical dynamics models. Empirical models are
widely used, and advanced versions have been used for train dynamics
simulations. Fluid dynamics models are better models to study brake
system behaviour but are more complex and slower in computation.
Fluid-empirical dynamics models combine fluid dynamics brake pipe
models and empirical brake valve models. They are a balance of model
fidelity and computational speeds. Depending on research objectives,
detailed models of brake rigging, friction blocks and wheel-rail adhesion
are also available. To spark new ideas and more research in this field, the
challenges and research gaps in air brake modelling are discussed.
