选取实测环境振动波和地震波,以加速度作为指标,深入研究TMD振动控制技术对竖向环境振动波的减振效果。研究表明:TMD对竖向环境振动的控制效果与输入振动波自身的特性有很大的关系,选择TMD作为减少竖向环境振动的技术措施时,需要明确结构所受环境振动波的特点,确保减振效果。
Based on actually measured environmental vibration wave and seismic wave, with the acceleration as the index,the vibration reduction effect of the vertical environmental vibration wave with TMD vibration control technology was studied further. The study shows that, the control effect of the vertical environmental vibration by TMD is grealty related with the self properties of the input vibration wave. When the T M D is selected as the technical measure to reduce vertical environmental vibration, the characteristics of the environmental vibration wave acting on the structure must be defined clearly to ensure the vibration reduction effect.
