“…The self-powered MR Damper diagram is depicted in figure 3 . There scalability and magnetic functionality of MR dampers is discussed in terms of magnetic saturation is extended to provide a high performance (Hemanth, K et al, 2014). The comparison of 2-D Axisymmetric and 3-D MR Damper models were simulated (Gohil et al, 2013).…”

In this paper, a vibration control system with magnetorheological (MR) damper investigation is reviewed. At first a MR damper is investigated analytically using various finite element method software and the performance is investigated using experimental. The MR Dampers are designed and modelled for a scaled down setup. The application is in seismic resistance of buildings, automobile, physical and biological. Finally, the damper is investigated using various technique and methods used to study the performance is reviewed. This device reduces the vibration in both active and semi active control system effectively.

“…Whereas, some researchers [5] have analyzed the fluid flow through the annular gap by quasi-static analysis and CFD analysis of MR damper has been studied. The prior investigators [6] have considered the & Hemanth Krishna ckh4545@gmail.com magnetic saturation analysis of magnetorheological damper for single coil and double coil arrangement by using FEM and developed nonparametric model, based on magnetic flux density in the fluid flow gap. It has been conducted experimentation earlier [7] on the disk type MR damper and performed magnetic field analysis using FEM.…”

A magneto rheological (MR) fluid damper offers cost effective solution for semiactive vibration control in an automobile suspension. The performance of MR damper is significantly depends on the electromagnetic circuit incorporated into it. The force developed by MR fluid damper is highly influenced by the magnetic flux density induced in the fluid flow gap. In the present work, optimization of electromagnetic circuit of an MR damper is discussed in order to maximize the magnetic flux density. The optimization procedure was proposed by genetic algorithm and design of experiments techniques. The result shows that the fluid flow gap size less than 1.12 mm cause significant increase of magnetic flux density.

“…Response surface method was used to arrive at the mathematical model to represent the MR damper behavior. Hemanth et al [23] used finite element approach to study the saturation of magnetic field in MR damper. A nonparametric model of the MR damper was developed to improve the damping force with optimal current by using MATLAB Simulink.…”

The smart behavior of magneto-rheological (MR) fluid is used in the present work in designing, experimentally characterizing and analyzing a MR damper for automotive application using the twin-tube damper concept. A commercially available passive damper of a passenger van was tested to find the characteristic damping requirement of the vehicle. With this as reference, a twin-tube MR damper working in valve mode was designed and fabricated. The magnetic flux density induced in the fluid flow gap is maximized using Taguchi analysis and finite element method magnetics (FEMM) software. The FEMM results are validated by verifying with results obtained analytically using electromagnetic circuit theory. The MR damper filled with commercially available MR fluid was experimentally tested in damper testing machine. The results demonstrate that the force developed by the MR damper is indeed increasing with the value of the current supplied. At various frequencies of input oscillation, the energy dissipated by the MR damper in a single cycle increases significantly with current supplied. The novelty of this work is that a twin-tube MR damper working in valve mode was designed as a replacement for the passive damper used in a passenger van. The MR damper thus developed is capable of producing practical levels of damping force at actual operating frequencies and amplitudes of the passive damper in the passenger van. For further analysis, the behavior of the MR damper is modeled by using the Bouc-Wen model for hysteretic systems. A proportional-integral-derivative controller is used to track the desired damping force in time domain to demonstrate the application of the MR damper in a semi-active suspension system.
