摘要

传统颗粒阻尼器在振动强度较高的情况下存在能量损耗效率低的缺陷，通过实验发现在颗粒阻尼器中内置三维网络结构（障碍网络）可以改善上述难题。为了探究内置障碍网络对颗粒运动状态及能量损耗的影响机理，采用离散元方法建立内置障碍网络的颗粒阻尼器数值模型并开展实验验证，研究振动参数和填充比对有无障碍网络颗粒阻尼器的耗能影响，探讨颗粒阻尼器内部颗粒碰撞及能量损耗空间分布特性。结果表明，在30~160Hz、2.5~25g振动条件及50%~90%填充比条件下，障碍网络能够改变颗粒群体运动行为以及增强其能量耗散性能；使原本对能量耗散几乎没有贡献的颗粒产生剧烈运动，参与到能量耗散过程；障碍网络使底部空间颗粒群体在一个振动周期内产生倍频的碰撞特性，极大增加能量损耗。

Abstract

Traditional particle dampers have the defects of low energy loss efficiency under the condition of high and low vibration intensity. Through experiments, it is found that three-dimensional network structure (obstacle network) built into particle dampers can improve the above problems. To explore the built-in barriers network of particle motion and the energy loss mechanism, the influence of the discrete element method is adopted to establish the internal obstacles network of particle dampers numerical model and experimental verification, the vibration parameters and filling ratio on particle dampers have barrier-free network of energy dissipation effect, discusses particle dampers inside particle collision and energy loss distribution characteristics. The results show that the barrier network can change the movement behavior of particles and enhance their energy dissipation under the conditions of 30-160Hz, 2-25g vibration and 50%-90% filling ratio. The particles, which had no contribution to the energy dissipation, moved violently and participated in the energy dissipation process. The barrier network makes the particle population in the bottom space produce double frequency collision characteristics in one vibration cycle, which greatly increases the energy loss.
