A numerical investigation on passive suppression of the parametric instability phenomenon using a rotative non-linear vibration absorber

摘要

This paper presents a numerical investigation on the use of a rotative non-linear vibration absorber (NVA) as a passive suppressor for the parametric instability phenomenon. Focus is placed on the influence of the mass, the radius and the damping of the NVA on its capacity to reduce the amplitudes of the cylinder in which it is installed.
