摘　　要：将活性炭颗粒作为减振剂,置入颗粒阻尼器与颗粒碰撞阻尼器中,通过试验研究这两类阻尼器对主振系统的减振性能,并将试验结果与多体碰撞阻尼器进行对比。结果表明,颗粒阻尼器的减振效果明显比多体碰撞阻尼器差;颗粒碰撞阻尼器虽然比多体碰撞阻尼器的减振效果稍差,但对抑制多体碰撞阻尼器的强非线性有着良好的效果,并且在一定的共振区域内,颗粒填充率对于颗粒碰撞阻尼器也存在一个最佳值。The activated carbon particles as damping agent were put into the particles damper and the fine particles impact damper. With the experimental method, the two kinds of damper＇s damping performance on the main vibraten system were studied. The experimental results of the fine particles impact damper were compared to the multiunit impact damper. The results indicated that the particles damper＇s damping performance was not better than the multiunit impact damper obviously, and the fine particles impact damper＇ s damping performance was slightly worse than the multiunit impact damper, but it had a good effect to suppress the strongly nonlinear of the multiunit impact damper. In a certain resonance region, there was an optimum filling rate for the fine impact damper.
