A vehicle/track/soil model using co-simulation between multibody dynamics and finite element analysis

Due to the always growing computing power, virtual models become nowadays a popular mean to simulate complex problems such as vehicle stability, track settlement or ground-borne vibrations induced by railway vehicles. This paper presents a co-simulation model of a vehicle passing on a track that lays on a soil. The model is split into two subsystems that are the vehicle and track subdomains and the soil subdomain. The coupled vehicle/track subsystem is modeled into an in-house multibody dedicated software package while the soil is entirely modeled with the help of a finite element analysis software. The results obtained using Jacobi and Gauß-Seidel methods, two different co-simulation techniques, will be compared to an already validated two-step model. Moreover, besides the results, this paper presents the coupling technique used between both subsystems to allow co-simulation and depicts the data management between the two distinct simulation environments.
