Particle Impact Damping (PID) is a passive vibration damping technique in which metal particles of small in size are placed in the enclosure attached to the vibrating structure at the highest amplitude region. The particle-particle and particle-wall collisions take place due to vibratory motion of the primary structure; hence the structure and the particles exchange the momentum and thus dissipate kinetic energy, consequently suppression of vibrations of primary structure. Due to its simplicity and potential effectiveness over wide temperature range and low cost, PID makes a better substitute to conventional damping techniques. Hence the particle damper has been successfully used to suppress the vibration of various machines such as, turbo machinery blades, bank note processing machine, space shuttles, turbine blades etc.
The primary objective of this work is to study the damping effectiveness of particle impact damping using multibody dynamics software MD-ADAMS. The simulations have been carried out for undamped beam, beam with added mass and beam with steel and lead particles. It is concluded that, the damping performance mainly depends on number, size and material of the particles.
