将颗粒碰撞阻尼器和动力吸振器相结合，提出了一种颗粒碰撞阻尼动力吸振器设计概念，该吸振器由一个装有碰撞颗粒材料的盒体和一个弹性元件组成，碰撞颗粒在盒体运动时发生碰撞而消耗能量。以一个五层的楼房框架模型为振动抑制对象，对其吸振性能进行了实验研究，并与相同质量的经典单质块动力吸振器的抑振效果进行比较。实验结果表明，所设计的颗粒碰撞阻尼动力吸振器扩展了经典的单质块动力吸振器的工作频率范围，对宽频带随机激励的振动响应具有良好的抑制效果，这种颗粒碰撞阻尼动力吸振器设计思想可以应用于高层建筑的地震和风振响应控制。

A new type of particle impact damped dynamic vibration absorber, which consists of a elastic element and a box partially filled with impact particles, is designed and used in the vibration control of a five-storey frame structure model. The dynamic properties of this type of damped dynamic vibration absorber are experimentally compared with these of the classical dynamic vibration absorber, which has the same mass and stiffness as the damped absorber. The frequency response functions (FRFs) of the frame structure with these two types of absorbers are measured respectively, it is shown that the particle impact damped absorber has a wider frequency band than that of the classical absorber. Vibration control test results of the frame structure subjected to random excitation demonstrated that the particle impact damped dynamic vibration absorber exhibits a better random vibration absorption behavior than that of the classical dynamic vibration absorber. It is expected that this new type of dynamic vibration absorber can be applied in the control of seismic and wind excited vibration response for tall buildings.
