| 摘 要： | 本文将磁流变(MR)阻尼器与普通橡胶隔震支座相结合，组成智能基础隔震系统应用到结构控制中。在详细介绍了系统的各部分与整体运行情况后，采用LQR经典线性最优控制算法对结构进行了振动台试验研究。试验结果表明，由MR阻尼器提供可调阻尼力的智能隔震控制系统，能有效克服被动隔震最优控制频带窄的缺点，对较宽频域范围地震激励能进行有效的振动控制。其相对一般被动隔震装置，能同时减小上部结构加速度和隔震层位移.

| Abstract: | In this paper, smart base isolation system consisting of rubber bearing and MR damper is applied to structural vibration control. The running conditions of each part and whole of the system are introduced. Then shaking table test employing LQR classical linear optimal control algorithms is performed.Test results indicate that the smart isolation system with MR damper providing adjustable damping forces can supply effective control for earthquake ground motion of different magnitudes in broad frequency domain and overcome above shortcoming that optimal central extent of passive isolation is narrow. Compared with passive isolation equipment, it can reduce both acceleration of superstructure and displacement of isolation layer. |
