摘　　要：圆柱调谐液体阻尼器的经典控制理论有其适用范围,风电柔塔的2阶振动不符合经典控制理论基本假定条件。文中先用流体数值分析软件对圆柱调谐液体阻尼器内部流体进行动力学求解,再用自定义函数作为流固耦合接口,根据Runge-Kutta算法完成柔塔运动学分析。研究结果表明:流固耦合数值结果为经典控制理论结果的32.6%,经典控制理论结果过高预测了圆柱调谐液体阻尼器对柔塔的控制效果。最后,对柔塔进行了模态测试,采用随机状态子空间法(SSI)得到了柔塔的2阶阻尼比。测试结果表明:流固耦合的数值结果更接近圆柱调谐液体阻尼器的实测效果。The classical control theory of the cylindrical tuned liquid damper can be applied in certain fields;the secondorder vibration of the wind turbine’s soft tower does not meet the basic assumptions of the classical control theory.In this article,firstly the fluid numerical analysis software is used to solve the dynamics of the fluid in the cylindrical tuned liquid damper.Then,the user deifne function is used as the fluid-solid coupling interface;the analysis is conducted on the soft tower’s motion according to the Runge-Kutta algorithm.The results show that the numerical results obtained from fluid-solid coupling are 32.6%of those obtained from the classical control theory,which overpredict the control effect of the cylindrical tuned liquid damper on the soft tower.Finally,the soft tower is subject to the modal test;the second-order damping ratio of the soft tower is identified with the help of the SSI method.It is shown that the numerical results obtained from fluid-solid coupling are closer to the measured results of the cylindrical tuned liquid damper.
