能量集中耗散与调谐质量阻尼系统

Gathering and wasting of energy vs. passive tuned mass damper

提出用能量集中耗散的方法替代调谐质量阻尼器，被动控制结构的地震响应．采用摩擦耗散能量，放弃了粘滞阻尼．通过角频率和振型分析探讨了能量集中的原因和最佳集能系统的参数．

It is presented that the method of gathering and wasting of energy can be used to substitute for the method of passive tuned mass damper,in order to control the response of structural vibration caused by seismic load.Instead of viscous damping,the frictional damping is used.The causes of the gathering of energy and the best parameters of the energy gathering system are discussed through the analysis of pulsatances and modes of structural vibration.The effect of reduction of vibration by different coefficients of friction is illustrated by digital emulation.
