粘弹性阻尼器隔震结构的振动控制研究

对设置粘弹性阻尼且基础隔震结构的混合振动控制问题进行了研究.采用开尔文模型模拟粘弹性阻尼器所产生的非线性力,推导出混合控制的运动微分方程,结合线性二次型最优控制理论（LQR）,用MATLAB编制相应的动态仿真程序进行动态仿真.研究结果表明：设置粘弹性阻尼器隔震结构采用混合控制是有效的,结构的隔震层相对位移和顶层位移反应大大降低.

Study on the Vibration Control of a Base-isolation Structure with Viscoelastic Damper

In this paper,the hybrid control of a viscoelastic structure with base-isolation has been researched.The energy dissipation ability of the visco-elastic damper is simulated by KELVIN model.Based on the modern control theories,the differential equations of the motion of the hybrid controlled structure are derived with dynamic simulation carried out through the MATLAB.The study results show that the hybrid control for the base-isolation structure with viscoelastic damper can improve efficiency of control for vibration.
