颗粒阻尼耗能原理和惯容增效原理在结构减振控制中得到了广泛应用，基于颗粒阻尼和惯容的优点设计一种颗粒阻尼惯容减振器（particle-damping inertial capacity shock damper, PID），其内部主要包含颗粒阻尼单元、惯性质量单元以及刚度单元。首先，阐述PID的工作原理，建立单自由度PID减振结构的力学分析模型；并制作一个小型PID实物模型，设置多种工况对PID进行力学性能测试；然后，利用多体动力学软件和离散元软件联合仿真的方法进一步对PID的力学性能进行探究；最后，为验证其工程应用价值，通过有限元结构分析软件SAP2000对配置PID和调谐质量阻尼器（tuned mass damper, TMD）的减振结构进行动力时程分析。结果表明：PID具有优良的减振性能，当其他条件一定时，PID耗能效果随着振动位移幅值和振动频率的增大而增大；在建筑结构中，PID表现出比TMD更佳的减振能力，具有较高的工程应用价值。

The principle of particle damping energy consumption and inertial capacity efficiency increase are widely used in structural vibration reduction control. Based on the advantages of particle damping and inertial capacity, a particle damping inertial capacity shock damper (PID) was designed, which mainly contained particle damping unit, inertial mass unit and stiffness unit. Firstly, the working principle of PID was elaborated, the mechanical analysis model of single degree of freedom was established, a small PID mock-up was produced, a variety of working conditions were set up to test the mechanical properties of the PID. Then, the mechanical properties of PID were further explored by the combined simulation method of many-body dynamics software and discrete element software. Finally, to verify its engineering application value, dynamic time-course analysis of the damping structures configured with PID and tuned mass damper (TMD) by finite element structural analysis software SAP2000. The results show that PID has excellent damping performance, when the other conditions are certain, the energy consumption effect of PID increases with the increase of vibration displacement amplitude and vibration frequency. In the building structure, PID shows better damping than TMD, it has a high engineering application value.
