Coupled Multibody‐Aerodynamic Simulation of High‐Speed Trains Manoeuvres

A co‐simulation MBS/CFD was implemented to investigate the effects of unsteady aerodynamic loads on the driving dynamics of high speed trains during common manoeuvres in absence of cross wind. A linear aerodynamic model, the panel method, was applied to the computation of the flow around the driving trailers and the multibody simulation program SIMPACK simulated the dynamic response of the vehicles to the resulting aerodynamic loads.
