摘要

Design a cylindrical particle damper, according to particle damper characteristics of simple structure, high reliability and poor working environment adaptability, etc. After comparing with the traditional liquid damper, using impact test study of particle damper, and analyzing resistance-displacement and resistance-speed mechanics characteristic curve, to analyze the influence laws of the various components of the damping energy consumption. And to identify the cases of the particle damper performance failure most likely to occur when subjected to impact, demonstrate the feasibility of particle damper dissipate impact energy, and provide sufficient experimental basis for further optimizing the design of the particle damper.%针对颗粒阻尼器具有结构简单、可靠性高和适应恶劣环境工作等优点，设计一款圆柱形颗粒阻尼器。经过与传统液体阻尼器的分析对比，利用冲击试验对颗粒阻尼器进行研究，通过阻尼器阻力-位移和阻力-速度等力学特性曲线深入分析各部件对阻尼能耗的影响规律，并找出颗粒阻尼器在经受冲击时最可能出现性能失效的情况，证实了颗粒阻尼器耗散冲击动能的可行性，为颗粒阻尼器进一步的优化设计提供了充分的实验基础。
