    Abstract: This study considered a slender hinged-free beam with suspension cables simulated using nonlinear springs.
    We added a time-dependent boundary dynamic vibration absorber (DVA) that was suspended at the free end of the beam to reduce vibration and prevent internal resonance. DVA with various spring constants were considered and the optimal mass range for the DVA to reduce vibration in the main structure was also proposed.

    Cette recherche porte sur l’examen d’une poutre fine à extrémité libre avec câbles de suspension à ressorts non-linéaires. Nous avons ajouté un amortisseur dynamique de vibration aux limites dépendantes du temps (ADV), lequel est suspendu à l’extrémité libre de la poutre pour réduire la vibration et pour prévenir la résonance interne. Des ressorts aux constantes variées furent considérés, et la portée massique optimale pour l’ADV, dans le but de réduire la vibration de la structure principale, a été proposée.
