摘　　要：用Bernoulli方程建立调谐液柱阻尼器(tuned liquid column damper,TLCD)的运动方程,得到非线性阻尼项,并采用能量等效原则得到等效线性阻尼。通过对TLCD运动方程中的非线性阻尼项和等效线性化分别进行模拟,分析结构振动响应的影响。用一47层高层结构作为算例,结果表明考虑非线性阻尼的TLCD的减振效果略优于等价线性化的TLCD。Tile equation of relative motion of the liquid in a tuned liquid cohmm damper （TLCD） can be derived using the ex- tended non-stationary Bernoulli＇ s equation. The method of equivalent linearization is commonly used to approxi- mate the nonlinear loss term by an equivalent linear one. The simulations of the linear/nonlinear system have been pertbrmed using Simulink. The numerical simulation is presented the TLCD with nonlinear damping is slightly su- perior to a TLCD with linear damping.
