弹性支撑颗粒碰撞阻尼的设计与实验研究

为了改善传统碰撞阻尼器对低频机械振动的减振性能，设计了一款新型的弹性支撑碰撞阻尼器。在阻尼器上加 上了弹簧作为弹性支撑，使得阻尼器与主系统之间产生充分的能量交换，可以进一步提高减振效果。通过设计对比实验 验证了阻尼器的减振性能，分析了弹簧刚度对减振特性的影响。实验证明弹簧的使用使阻尼器的减振性能得到提高，而 且对低频振动的减振效果远比其它类型的阻尼器好。弹簧刚度对阻尼器性能具有一定的影响，弹簧刚度存在最佳值。

Design and Experimental Study of Particle Impact Damper with Elastic Support

ln order to improve the vibration reduction performance of the traditional impact damper on the low frequency mechanical vibration, a new type of elastic support impact damper was designed. Springs were added on the damper as elastic support, and the energy exchange between the damper and the main system could be produced more fiercely, which could further improve the effect of vibration reduction. The damping performance of the damper could be verified, and the influence of the spring stiffness on the vibration characteristics could be analyzed , by comparing the experimental results of the designed contrast experiments. The experimental results show that the vibration performance of the damper is improved by using the springs, and the vibration on the low frequency vibration is better than other types of dampers. The spring stiffness has a certain effect on the performance of the damper, and the spring stiffness has the best value.
