中文摘要：
提出了抑制水平振动的磁流变式调谐液柱阻尼器（MR—TLCD）模型，建立了单自由度结构——MR—TLCD的耦合运动方程。从系统动力方程出发，根据离复位控制策略，确定了MR—TLCD与单自由度结构相互作用过程中的合理阻尼大小。数值计算中，利用谐波叠加法模拟风荷载作用于该系统，并通过调节MR—TLCD的电压进行实时控制。仿真结果说明了在离复位控制策略下，MR—TLCD用于结构风振控制的合理性和有效性，是理想的半主动控制装置。
英文摘要：
Magnetorheological tuned liquid column damper （MR-TLCD） is a new kind of device for vibration control. It has a good performance and can be realized in project easily. A theoretical model of MR-TLCD for suppressing horizontal vibration is developed. The structure with single degree of freedom--MR-TLCD interactive equations are formulated. To start from the dynamic equations of system, the reasonable damping of MR-TLCD is determined according to the off-and-towards-equilibrium control strategy. In numerical calculation, wind load which is simulated by superposition of harmonic acts on the system. The control in time is carried out by adjusting the voltage of MR-TLCD. The simulation results show that the proposed is feasible and effective. Besides, MR-TLCD is an optimal semi-active control device.
