MARTINOD R, Ronald M; BETANCUR G, Germán R  e  CASTANEDA H, Leonel F. Evaluating damping elements for two-stage suspension vehicles. Ing. Investig. [online]. 2012, vol.32, n.1, pp.11-17. ISSN 0120-5609.

The technical state of the damping elements for a vehicle having two-stage suspension was evaluated by using numerical models based on the multi-body system theory; a set of virtual tests used the eigenproblem mathematical method. A test was developed based on experimental modal analysis (EMA) applied to a physical system as the basis for validating the numerical models. The study focused on evaluating vehicle dynamics to determine the influence of the dampers' technical state in each suspension state.

Palavras-chave : eigenproblem; EMA; multi-body model; modal parameters; suspension system; railway vehicle.
