abstract
Particle impact damping (PID) is a meaas for increasing component fatigue life by reducing structural vibrations. A particle-filled enclosure attached to an area of high velocity converts kinetic energy into heat through inelastic inter-particle and particle-enclosure collisions. The experimental study shows that for components experiencing transient vibrations in the horizontal plane (perpendicular to gravity), significant damping (30% per cycle) can be achieved at very low acceleration amplitudes (below Ig) through the use of particle impact damping.
