“…The characterization of particle damping has also been attempted by Mao et al [17], using discrete element method which simulates the behavior of granular materials in three-dimension. Different modeling and simulation approaches have been used by Xu et al [42] and Bai et al [3] for prediction of the damping effect and to have better insight and understanding of PID.…”

This paper presents a novel method, based on the particle impact damping (PID), for the attenuation of regenerative vibration in boring operation. A specially designed boring bar having a cavity near machining-end for partial filling of spherical particles has been developed. Characteristics of boring bar with and without PID have been found from impact and shaker tests. After identifying appropriate particle size and filling volume, experiments are conducted to evaluate the performance in actual boring operations. Additional boring experiments are also conducted to confirm the performance by changing particle size and filling volumes. The collision of the particles in PID is found to attenuate regenerative vibration by the energy dissipation and thus effectively enhances stability of the boring operation. Analysis of effect of PID on surface topography in terms of chatter marks, surface roughness, and roundness of bored holes shows that the proposed method results in improvement of bore quality when compared with a boring bar without PID. It is also established that radial vibration of the boring bar has a significant influence on the surface topography obtained in boring operation.

“…The response of an oscillating cantilever with respect to periodic forcing has also been studied [25][26][27][28][29][30]. Even more complex systems have been investigated, such as the oscillation modes of a plate with an abundance of granulate filled cavities [31][32][33][34] with the aim of noise reduction [19]. For simple systems, such as cantilever oscillators, some progress has been made.…”

The response of an oscillating granular damper to an initial perturbation is studied using experiments performed in microgravity and granular dynamics simulations. High-speed video and image processing techniques are used to extract experimental data. An inelastic hard sphere model is developed to perform simulations and the results are in excellent agreement with the experiments. The granular damper behaves like a frictional damper and a linear decay of the amplitude is observed. This is true even for the simulation model, where friction forces are absent. A simple expression is developed which predicts the optimal damping conditions for a given amplitude and is independent of the oscillation frequency and particle inelasticities.

“…Zhiwei Xu et al [10] investigated a structure in which damping particles were embedded in the horizontal hole drilled in the vibrating structure. They concentrated on the study of shear of the boring bar and its effects on the damping capability of the structure.…”
