摘要

本文对新设计的一种新型磁流变阻尼器的力学性能进行了试验研究。通过试验,建立了阻尼器的力学模型。将阻尼器安装在一1:6三层钢框架结构模型上,进行了模拟地震振动台试验。试验中采用被动和半主动控制方法,输入不同的地震波,对结构进行了振动控制研究,了解半主动变阻尼结构的动力特性。振动台试验结果表明,在输入不同地震波时,被动控制的减振效果变化较大,而半主动控制对结构在不同地震波输入下均有较好的减振效果,另外,磁流变阻尼器在结构中的安装位置不同对结构的减振效果也有一定的影响。最后论文对比研究了被动控制结构和半主动控制结构动力反应试验结果及弹塑性分析结果,试验与计算结果符合较好。
A new kind of magnetorheological damper(MRD) was designed with experimental studies on mechanical performances conducted. The nonlinear hysteretic biviscous model to describe the performance of the MRD was established,and a 1:6 scale three story steel structure with and without the semi active damper was tested on a shaking table under earthquake ground excitations. The shaking table test results indicate that under the circumstances of different input excitations and various acceleration amplitudes, the semi active controller achieves higher performance levels as compared to those of the passive control systems. Furthermore, the installation locations of the MRD in the building also affects the vibration suppressed results. The predicted numerical results are in good agreement with the experimental results, and they verify the correctness of the theoretical model.
