“…19,20 Recently, some small MRF dampers are developed, such as the RD-1097-01X damper is the smallest commercial damper, whose force is still 100N. 21 The structure of the traditional MRF damper is shown in Figure 1. The magnetic coil is configured inside the damper, and wires inside the coil have to be drawn out through the axial center hole.…”

In order to realize small loading and small damping, a mini Magneto-rheological fluid (MRF) damper is suggested by using new method of outer coils, and its physical model is established firstly. It was found that the landing force is only 1.74∼8N, the landing force is the third-order function with the current by polynomial fitting of the experimental data, which shows a force-current model. The results of force-displacement and force-velocity indicate that it has nonlinear hysteretic damping characteristics. Based on the new mini-mode principle and the damping characteristics, an improved nonlinear dynamics model is proposed, and its parameter expressions are obtained by parameter identification and regression fitting. Model curves fit well with experimental curves, and the improved model has fully demonstrated the dynamic characteristics of the mini-MRF damper. It will provide scientific method and physical model for the small MRF damper development.

“…However, the non-parametric damper models are quite complicated. Gamato and Filisko [56] proposed a parametric viscoelastic-plastic model based on the Bingham model. Wereley et al [7] developed a nonlinear hysteretic biviscous model, which is an extension of the nonlinear biviscous model having an improved representation of the pre-yield hysteresis.…”

The magnetorheological (MR) damper is one of the most promising new devices for structural vibration reduction. Because of its mechanical simplicity, high dynamic range, low power requirements, large force capacity and robustness, this device has been shown to mesh well with application demands and constraints to offer an attractive means of protecting civil infrastructure systems against severe earthquake and wind loading. In this paper, an overview of the essential features and advantages of MR materials and devices is given. This is followed by the derivation of a quasi-static axisymmetric model of MR dampers, which is then compared with both a simple parallel-plate model and experimental results. While useful for device design, it is found that these models are not sufficient to describe the dynamic behavior of MR dampers. Dynamic response time is an important characteristic for determining the performance of MR dampers in practical civil engineering applications. This paper also discusses issues affecting the dynamic performance of MR dampers, and a mechanical model based on the Bouc-Wen hysteresis model is developed. Approaches and algorithms to optimize the dynamic response are investigated, and experimental verification is provided.

“…There are several MR damper models proposed in the literature, in order to describe their non-linear and hysteretic responses [3,4,8,14,16,28]. One of the most extensively used models to describe the non-linear hysteretic behaviour of a MR damper is the Bouc-Wen model, proposed by Spencer et al [24].…”

., Díaz, V. (2017 (1) it is based on algebraic functions instead of differential equations, so that it does not present convergence problems when noisy inputs from exper-imental measurements are used; (2) the number of parameters is reasonable, so that it makes the model computationally efficient in the context of parameter identification and (3) the model has to take into account the variation of the parameters as a function, not only of the applied current but also of the frequency of excitation. Experimental results confirm that the proposed frequency dependent MR damper model improves the accuracy of the model in force simulation.
