    Evaluating damping elements for twostage suspension vehicles
    (UNIV NAC COLOMBIA, FAC INGENIERIA, 2012-01-01) Martinod R, R.M.; Betancur G, G.R.; Castañeda H, L.F.; Universidad EAFIT. Departamento de Ingeniería Mecánica; Estudios en Mantenimiento (GEMI)
    The technical state of the damping elements for a vehicle having twostage suspension was evaluated by using numerical models based on the multibody 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.
