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.

 

El trabajo plantea la evaluación del estado técnico de los elementos de amortiguación de un vehículo con dos (2) etapas de suspensión, por medio de modelos numéricos basados en la teoría de sistemas multicuerpo, a los cuales se aplica un conjunto de pruebas virtuales usando el método matemático de vectores propios. Se desarrolla una prueba basada en el análisis modal experimental (EMA) aplicada al sistema físico, como base para validar los modelos numéricos, y posteriormente el estudio se enfoca en la evaluación de la dinámica del vehículo para determinar la influencia del estado técnico de los amortiguadores en cada etapa de suspensión.
