Virtual pantograph-catenary environment for control development based on a co-simulation approach

Multibody dynamics methodologies have the potential to integrate in a unique simulation environment different disciplines, each one with its own equilibrium equations and computational methods. The key issue is not so much ability include modelling solution methods same computer code, but more possibility handle codes, eventually programmed languages using their numerical methods, which they exchange data controlled efficient form. Such an codes co-exist coordinated time stepping procedures defined as co-simulation. In this work, co-simulation multibody code simulated concurrently finite element presented demonstrated. main goal behind development develop virtual scenario of realistic interaction between train roof-mounted pantographs overhead contact line, also known catenary, paradigms for mechatronic can be tested. tool pantograph, while catenary modelled simulated. Each has integration algorithm, require that motion both models are solved at instants. This paper proposes coordination strategy input-output required by integrators complete environment. methodology demonstrated study objectives providing test ground identifying maximum operation velocity pantograph-catenary couple operate.
