particle damping, boring bar, vibration control
Particle damping offers potential for designing a better passive damping technique with a minimal impact on the strength, stiffness and the weight of a vibrating structure. Due to its conceptual simplicity, potential effectiveness over a wide frequency range, temperature and degradation insensitivity, and cost-effectiveness, particle damping is an attractive passive damping. This paper investigates the efficiency of particle damping in control of vibrations in a boring bar using copper and lead particles of various sizes. Their damping performances were compared and the results are presented.
