摘　　要：本文介绍了采用ＴＬＤ（调频液体阻尼器）和ＡＭＤ（主动质量阻尼器）对南京电视塔风振反应进行混合控制的分析方法。文中，推导了ＴＬＤ对结构风振反应的控制力和控制效果的等效阻尼比，介绍了悬吊ＡＭＤ对设置ＴＬＤ结构脉动风振反应的最优控制分析方法。并在产生南京电视塔广义脉动风荷载样本的基础上，对混合控制的效果进行了计算机模拟。计算结果表明，采用ＴＬＤ和ＡＭＤ对南京电视塔进行混合控制的效果是好的，可满足小塔楼的舒适度要求。The analysis method of hybrid vibration control applying TLD (Tuned Liquid Damper) in combination with AMD (Active Mass Damper) to Naming TV Tower under wind excitation is introduced in this paper. The equations for computing the structural response control force of TLD under wind vibration and the equivalent damp ratio of TLD are first derived. The analysis method of optimal control of the suspended AMD to the pulse-wind vibration reaction of'tower with TLD is also presented. Then, based on the formation of the generalized pulse wind load of Naming TV Tower, the simulation calculation of hybrid vibration control of Naming TV Tower has been carried out by computer.The results show that the hybrid control of TLD and AMD has good effect and can satisfy the design requirement of human comfort for the small sightseeing hall.
