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
