| 摘 要： | 本文中作者将新型双磙子FPS系统的动力学方程推广到由滚动FPS和MR阻尼器组成的混合隔震基础系统,得到了更便于应用的水平分量形式的运动微分方程,并将与FPS有关的力和MR阻尼力处理成力源项,构造了可以方便地考虑不同上部结构形式的MATLAB/SIMULINK仿真模型。采用RD-1005型MR阻尼器和模糊逻辑控制器,在两个典型的地震输入情况下对混合系统进行了振动控制仿真。仿真结果表明,本文建立的混合隔震基础系统的动力学模型是正确和精确的,直接利用动力学模型进行前向计算可避免附加的模型误差且计算效率高,而仿真模型中将不同的力源由分开的块组成,使得仿真设计非常方便快捷。

| Abstract: | Based on the equation of motion for the novel FPS with dual rollers by the authors in previous studies,the equation is extended for a hybrid base isolation system including the novel FPS and MR damper,which is then adapted to a more applicable form in terms of the horizontal component.A MATLAB/SIMULINK model for simulating the hybrid base isolation system is constructed,which allows the different kinds of upper structures to be incorporated.The simulation,in which the RD-1005 type of MR damper and the fuzzy logic controller are applied,is carried out for different typical earthquake excitations.The results show that the dynamic model of the hybrid base isolation system is correct and precise for the study of the dynamic behavior of the hybrid base isolation system,since it eliminates additional errors.The simulation model including separated S-function blocks is built according to the dynamic model,which will facilitate the design of the hybrid base isolation system including the novel FPS and MR damper. |
