TLD减小钢桥塔涡激振动的原理及应用研究

讨论了TLD（Tuned Liquid Damper）的减振机理，并用解析形式给出了TLD对结构控制的减振力，求出了TLD与结构相互作用时结构的位移响应，推导了结构安装TLD后结构的等效阻尼比，给出了结构的减振效率，验证了TLD减振效果非常好，可以保证桥塔建设过程中的施工安全。

Principle of reducing vortex-induced vibration of steel bridge tower by TLD

The following paper discusses the vibration reduction mechanism of TLD, gives out damping force of TLD on structural control by parsing form, calculates displacement response of structure at the time of interaction between TLD and structure, derivates equivalent damping ratio of structure after installing TLD, points out vibration reduction efficiency of structure, and validates the well vibration reduction effect of TLD, which to ensure construction safety in the process of building bridge tower.
