| Abstract |
The unified formalism of bond graphs is applicable to designing, modeling and analyzing complex
and heterogeneous physical systems. Moreover, various order-reduction methods can be applied
directly on bond graph models in order to simplify them. The aim of this paper is to demonstrate the
characteristics and the advantages of the bond graph formalism, considering as an example, model
simplification methods of a railway traction system. Several simulations are carried out in order to
validate the simplified models. The analysis of couplings on these models highlights the elements that
cause perturbations, such as mechanical resonance. |
