| 摘 要： | 研究MR智能基础隔震结构的抗震性能。首先,建立该混合控制结构的数学模型,其中应用双线型恢复模型描述橡胶垫隔震层的弹塑性特性,运用自适应神经网络模糊系统(ANFS)计算MR阻尼器的控制力。在SIMULINK环境下对控制结构进行仿真动力分析。并对具体结构进行地震作用下的时程反应分析,仿真分析表明:自适应神经网络模糊系统可以有效地应用到结构控制中,并证实了MR基础隔震结构是一种性能优异的智能控制系统。

| Abstract: | The performance of intelligent base-isolated structure with MR damper for suppressing the seismic response is studied.The numerical model of the hybrid control system is established,and the bilinear hysteretic model is applied to simulate the hysteretic characteristics of the rubber bearing isolation cushion.ANFS controller is designed to calculate the force of the MR damper.The SIMULINK method is adopted to solve the dynamic differential equations.Based on the seismic dynamic time history response of some ... |
