摘要
本文提出了根据输入地震波的加速度功率谱密度设计用于消减结构随机振动的动力减振器的思想及设计方法 ,并利用多种不同地震波通过计算机仿真进行了险证。
In the paper the idea of reducing structure vibration by DVA (Dynamic Vibration Absorber) under random stimulus is presented and the design method according to the power spectral density of acceleration of earthquake-wave is suggested.Computer simulation is used to examine the effect of DVA under some kinds of earthquake-waves.The results show it is feasible by using DVA to decrease structure vibration under earthquake-wave excitation.
