首发时间:2006-03-28
摘要:基于MR阻尼器修正的Bingham模型,采用Matlab模糊工具箱进行了模糊半主动控制策略的设计,并应用Simulink模块机进行了仿真分析,比较了多层框架原结构和几种基础隔震结构的模拟地震响应。结果表明,模糊半主动控制基础隔震能有效减小隔震层和上部结构的位移、加速度。

Fuzzy Semi-active Control with Multi-story Structure of Base-isolation System
Abstract:A modified Bingham model was proposed to simulate the machinery property of smart damper. Simulation analysis was carried out to multi-story structure with fuzzy and with simulink toolbox in the current work. Through the comparison of the isolation indexes obtained by different base-isolation system, it could be seen that that fuzzy semi-active control system can significantly reduce the earthquake responses of upper structure and the isolation layer.
Keywords: fuzzy semi-active control, base-isolation system, multi-story, MR damper, simulink analysis
