| 摘 要： | 本文在现在磁流变阴尼器性能研究的基础上，提出了可调滞回模型的磁流变阻尼器及其试验方法，并进行理论、试验及算例分析。首先，根据恒定电流下磁流变阻尼器的阻尼力滞力特性，利用磁流变材料特性的电流（即磁场）可控特点，建立了变电流下的阻尼力滞回模型；其次，在中通过电路板控制外加电流与装置变形间的函数关系，实现了变电流调节的阻尼力滞回模型；最后，将磁流变阻尼器与橡胶隔震装置结合，形成智能磁流变隔夺装置，并对一个单自由度隔震结构进行了数值仿真分析。

| Abstract: | In this paper, based on the present research on magnetorheological (MR) damper performance, MR damper and experimental method with adjustable hysteretic model are developed, and comprehensive studies are carried out by theoretical, experimental and example analysis. Firstly, on the basis of the hysteretic characteristic of MR damper under constant electric current, the hysteretic models with variable electric current are established by taking advantage of adjustable electric characteristic of MR material. Secondly, damping force hysteretic models with variable electric current are realized in the experiment by controlling the functional relationship between external electric current and deformation of the device through circuit board.In the end, the traditional rubber isolation device is integrated with MR damper to obtain a smart MR isolation device, that is used to perform numerical simulation analysis in a single-degree-of-freedom (SDOF) system with isolation device. |
