Effective mass overshoot in single degree of freedom mechanical systems with a particle damper
, 2011 We study the response of a single degree of freedom mechanical system composed of a primary mass, M, a linear spring, a viscous damper and a particle damper. The particle damper consists in a prismatic enclosure of variable height that contains spherical

Flow Mode Magnetorheological Dampers with an Eccentric Gap
Advances in Mechanical Engineering, 2014 This paper analyzes flow mode magnetorheological (MR) dampers with an eccentric annular gap (i.e., a nonuniform annular gap). To this end, an MR damper analysis for an eccentric annular gap is constructed based on approximating the eccentric annular gap ...

ANTI-VIBRATION INSULATION POSSIBILITIES OF THE OVERGROUND PARKING OVER THE DAMBOVITA RIVER. ANTISEISMIC PROTECTION SYSTEMS [PDF]
Analele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2019 Too strong an excitation force cannot be applied to a resonant system, because it will develop vibrations of very large amplitudes. The damping is the one that controls the motion of a resonant system at its natural frequency.
