“…Spherical particles of 2.54 cm diameter made of tungsten were placed inside the damper. The dimensions of the damper's cavity and the number of particles were selected in order to satisfy the criteria suggested by Papalou et al [14][15][16][17]. Tungsten particles were selected because of their high density.…”

“…There have been several studies of the dynamic behavior of monuments consisting of classical columns [2][3][4][5][6][7][8][9][10][11][12][13] but there have been only limited efforts to investigate their seismic enhancement [14][15][16][17][18]. Previous research [14][15][16][17] suggested that particle dampers can be used to reduce the motion of a vibrating column. Particle dampers are passive control systems that absorb the incoming energy through impact of particles with each other and with the walls of the container resulting in exchange of momentum between the particles and the primary system.…”

“…Such devices have been used for years to reduce the vibrations of machines and structures [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. Papalou et al [14][15][16][17] reported that a properly designed particle damper replacing one of the top drums of a classical multi-drum column without capital can achieve substantial reduction of the motion. The particles inside the damper have to be placed in one layer, occupying 40-60% of the empty space and to have mass equal to 1-3% of the mass of the column.…”

“…The particles inside the damper have to be placed in one layer, occupying 40-60% of the empty space and to have mass equal to 1-3% of the mass of the column. Previous research on the effectiveness of particle dampers has focused only on multi-drum columns without capital [14][15][16][17]. There has been no published work, to the best of our knowledge, on the use of particle dampers on monolithic columns and on multi-drum columns with capital.…”

“…1). This paper, building upon the results obtained from previous research [14][15][16][17], examines the effect of particle damper's position on the dynamic response of multidrum and monolithic columns with a capital on top. Two small marble column-models are used, a monolithic and a multidrum one consisting of four drums.…”

Summary A particle tuned mass damper (PTMD), which is a creative integration of a traditional tuned mass damper and an efficient particle damper in the vibration control area, is proposed. This paper presents a comprehensive study that involves experimental, analytical, and computational approaches. The vibration control effects of a PTMD that is attached to a five‐story steel frame under seismic input are investigated by a series of shaking table tests. The influence of some parameters (auxiliary mass ratio, gap clearance, mass ratio of particles to the total auxiliary mass, frequency characteristics, and amplitude level of the input) is explored, and the performance of the PTMD with/without buffered material is compared. The experimental results show that the PTMD can achieve significant damping effects under seismic excitations, and the bandwidth of the suppression frequency is expanded, showing the device's robustness and control efficiency. In addition, an approximately analytical solution that is based on the concept of an equivalent single‐particle damper is presented, and the method to determine the corresponding system parameters is introduced. A comparative study between experimental and numerical results is conducted to verify the feasibility and accuracy of this analytical model. Copyright © 2016 John Wiley & Sons, Ltd.

Particle damping, an effective passive vibration control technology, is developing dramatically at the present stage, especially in the aerospace and machinery fields. The aim of this paper is to provide an overview of particle damping technology, beginning with its basic concept, developmental history, and research status all over the world. Furthermore, various interpretations of the underlying damping mechanism are introduced and discussed in detail. The theoretical analysis and numerical simulation, together with their pros and cons are systematically expounded, in which a discrete element method of simulating a multi-degree-of-freedom structure with a particle damper system is illustrated. Moreover, on the basis of previous studies, a simplified method to analyze the complicated nonlinear particle damping is proposed, in which all particles are modeled as a single mass, thereby simplifying its use by practicing engineers. In order to broaden the applicability of particle dampers, it is necessary to implement the coupled algorithm of finite element method and discrete element method. In addition, the characteristics of experimental studies on particle damping are also summarized. Finally, the application of particle damping technology in the aerospace field, machinery field, lifeline engineering, and civil engineering is reviewed at length. As a new trend in structural vibration control, the application of particle damping in civil engineering is just at the beginning. The advantages and potential applications are demonstrated, whereas the difficulties and deficiencies in the present studies are also discussed. The paper concludes by suggesting future developments involving semi-active approaches that can enhance the effectiveness of particle dampers when used in conjunction with structures subjected to nonstationary excitation, such as earthquakes and similar nonstationary random excitations. KEYWORDS discrete element method, impact damping, nonlinear energy sink, particle damping, passive control, semiactive control | INTRODUCTIONParticle damping technology is a form of an auxiliary-mass type vibration damper, wherein multiple metal, tungsten carbide, ceramic or other types of small particles are placed within the cavities of the vibrating structure, or the enclosures attached to the vibrating structure in order to mitigate the response of the primary structure. [1,2] As the primary structure vibrates, kinetic energy is significantly absorbed through the combined effects of particle-to-particle and particle-to-wall inelastic collisions and frictional losses, producing considerable damping to the primary structure. [3][4][5][6] Particle damping technology has been widely Received: 23 February 2017 Revised: used due to its conceptual simplicity, moderate cost, good durability, and temperature insensitivity. Provided that the operating temperature is below the particles' metal melting point, it could maintain normal operation. Furthermore, material such as tungsten powder can withstand the high temp...
