Importance of gravity and friction on the targeted energy transfer of vibro-impact nonlinear energy sink

The effect of gravity and sliding friction on the dynamics around targeted energy transfer an inclined vibro-impact nonlinear sink (VINES) is addressed. non-smooth first formulated in Signorini’s contact law treated using a Moreau-Jean scheme adapted with energy-conserving integration method. Exhaustive discussions are then carried out regarding vibration damping performance VINES, as well their dependence underlying induced response regimes, under both transient steady-state responses. It demonstrated that responsible for reducing barrier required achieving response, or enlarge existing bandwidth effective strongly modulated (SMR) which equivalent representation TET to improve considerably overall efficiency. Some adverse effects brought by also reported, it found that, when incline angle coefficient grows large, SMR reduces again leads deterioration results open door appropriately taking advantage into VINES design its performance.
