本文对合肥电视塔进行了动力特性分析 ,同时利用仿真得到的 19维脉动风压时程样本曲线 ,对塔的振动和控制分别进行了时域分析。计算结果表明 ,利用上塔楼生活和消防水箱构成调频质量阻尼器 (TMD)对合肥电视塔的风振有明显的控制作用。最优参数的TMD可使得电视塔上塔楼峰值加速度响应下降 5 4%
In this paper, the dynamical characteristics of Hefei TV Tower are analyzed. At the same time, the time-domain analysis of tower vibration and control are carried out respectively by using the 19-dimensional pulsatile wind pressure time history curve obtained by simulation. The calculation results show that the use of FMD damper (TMD) to control the wind-induced vibration of Hefei TV tower by using the tower life and fire water tank. The TMD of optimal parameters can reduce the peak acceleration response of the towers on the tower by 54%
