| 内容記述 | Particle damping is a technic providing damping with granular materials within vessels in a vibrating machine. The particle damper has been used successfully in many fields for vibration reduction. Particle-to-wall and particle-to-particle collisions occur under the vibration of the machine. By installing the particle damper to the machine, momentum between particles and machine is exchanged, and kinetic energy of the vibratory system is dissipated due to the friction generated among the particles and elastic deformation of particles. It is difficult to predict the damping characteristics due to complex motions of the particles in the damper vessel. In this paper, we utilized the discrete element method (DEM) to calculate the motion of particles in the vessel of the particle damper. In the simulation, motion of particles, forces exerted by the particles, and energy dispassion are calculated. The validity of the simulation is verified by comparison between experimental and simulation results. Experiments and simulations under some conditions are conducted under various conditions, and thus the relationship between the motion of particles and the damping characteristics of the particle damper are clarified. | |||||
