VIBRATION CONTROL BY USING PARTICLE DAMPER
Main Article Content
Abstract
Vibration is the most considerable domain in industries now a day. Particle damping (PD) is a means for achieving high-structural damping by the use of a particle filled enclosure attached to the structure in a region of high displacements. The particles absorb kinetic energy of the structure and convert it into heat through in elastic collisions between the particles and the enclosure, and among-st the particles. In this work, PD is measured for a cantilevered aluminum beam with the damping enclosure attached to its free end; Steel particles are used in this study. The effect of acceleration, amplitude and clearance inside the enclosure on PD is studied. Additional energy dissipation can also occur due to frictional losses and in elastic particle-to-particle collisions. The unique aspect of PD is that high damping is achieved by absorbing the kinetic energy of the structure as opposed to the more traditional methods of damping where the elastic strain energy stored in the structure is converted to heat. Particle impact damping offers the potential for the design of an extremely robust passive damping technique with minimal impact on the strength, stillness and weight of a structure.
