Analytical Investigation of MR Damper for Vibration Control: A Review

Abstract

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.

“…Among the myriad of MR devices, MR damper stand as one of the most sophisticatedly employed variants [4,7]. They are commonly utilized within vibration isolation systems, primarily accomplished through the modulation of device output damping via current control to cater to the diverse damping demands of the system under varying external excitation conditions [4,20,22]. Kim et al employed a MR damper in the nonlinear control of building structures and proposed a system design approach based on linear matrix inequalities.…”

“…The aforementioned studies demonstrate the significant advantages of MR dampers in semi-active control systems. However, in scenarios demanding sustained operational efficacy of MR damper even following extended periods of dormancy, such as in the fields of architecture, bridge construction, and elevator impact buffering, the issues of sedimentation and leakage in traditional MR fluids continue to serve as primary impediments to their widespread utilization [2,4]. In recent years, MR grease with a lubricating grease matrix have garnered significant attention due to their excellent sedimentation stability and resistance to leakage.…”
