“…作非牛顿流体，采用不同的本构关系建立基于 N-S 方程的流体力学模型，来预估其阻尼力。如孔祥东等 [7] 学者用 Bingham 流体模型来描述磁流变液的本构关系，并利用平行平板模型对同心环形流道进行简化建模，能够较为准确地得出理论阻尼力，但不能合理解释磁流变液阻尼器速度特性中的滞回现象；FALAH [8] 与 MANJEET [9] 等提出 Hershel-Bulkley 模型在 Bingham 模型的基础上能够更好地表征磁流变液的剪切稀化效应，更加准确地预测了阻尼器的示功特性，但同样存在滞回现象无法合理解释的问题。为合理表征滞回现象，杨永刚等 [10] 引入 Bouc-Wen 公式来表示滞回单元，由于其算法中微分公式的复杂性，磁流变阻尼系统中凡涉及的 Bouc-Wen 滞回单元存在实际工况中无法准确量化的问题；王修勇等 [11] 的实验测试表明，磁流变液阻尼器的速度特性中的滞回效应与励磁电流成正相关特性，产生速度特性滞回现象本质是磁流变液流动方向发生变化时存在过渡阶段；ZHANG 与 PENG [12] 在此基础上提出了预屈服阶段下的颗粒链化模型来表征过渡阶段，但颗粒链化模型预估示功特性还存在不足。上述理论模型研究 [7][8][9][10][11][12]…”

第 58 卷第 11 期期 144 quasi-static model in the yield phase were verified by using MTS testing machine. Using the above model, the influences of the parameters such as the number of coil turns, piston velocity, damping channel clearance and damping channel length on the adjusting range of magnetorheological fluid damper are analyzed. The results show that the particle chain model in the pre-yield stage can effectively predict the hysteretic effect, and the quasi-static model in the yield stage can effectively predict the indicator characteristics, and the coil turns and the length of the damping channel have more significant effects than other parameters, which provides a reference for the design of the same type of magnetorheological fluid dampers.

“…Good structures to support the piston rod and methods to con ne the direction of the load are needed due to the stretch state of the piston. Falah et al [14] developed one model for this kind of damper based on parallel plate analysis by using both Newtonian and Bingham shear ow mechanisms, and the model was validated through experimental testing of the damper.…”

Magnetorheological (MR) uids are a class of new intelligent materials whose rheological characteristics change rapidly and can be controlled easily in the presence of an applied magnetic eld. The devices based on MR uids, including dampers, brakes, clutches, polishing devices and hydraulic valves, etc., have a very promising potential future; some of them have been used commercially in engineering applications such as automobiles, polishing machines, exercise equipment, etc. In this paper, the modes of operation of MR uid devices are analysed. A comprehensive review is then presented of the principles, characteristics and engineering applications of the MR uid devices (especially dampers) studied in the last decade. Finally, the application prospects of MR uid devices are discussed.

“…Consequently, this pseudo-static model in the ideal state can be permitted in early design. For instance, Falah et al (1998) developed the damper model in terms of parallel plate analysis by using both Newtonian and Bingham shear flow mechanisms. Wereley also built a parallel plate model depending on a different set of dimensionless parameters.…”

Owing to the complex nonlinear hysteresis of magnetorheological (MR) damper, the modeling of an MR damper is an issue. This paper examines a novel MR damper hysteresis model based on the grey theory, which can fully mine the internal laws for the data with small samples and poor information. To validate the model, the experiment is conducted in the MTS platform, and then the experimental results are compiled to identify the model parameters. Considering the complexity of the grey model and its inverse model solution, the grey model is simplified in two ways based on the grey relational analysis method. Furthermore, the simplified grey model compares to other models to prove the superiority of the grey model. The analysis suggests the fitting results correspond to the measured results, and the mean relative error (MRE) of grey model is within 2.04%. After the grey model is simplified, its accuracy is slightly reduced, while its inverse model is easier to solve and makes a unique solution. Finally, compared with the polynomial and Bouc-Wen model, the novel model with fewer identification parameters has high accuracy and predictive ability. This novel model has fabulous potential in designing the control strategy of MR damper.
