Abstract
The Magnetorheological Fluid Damper stands out among various damping systems for its efficacy in mitigating vibrations and enhancing performance. Compared to conventional viscous dampers, MR fluid dampers have demonstrated superior effectiveness [1]. The concept of Magnetorheological (MR) fluid was initially introduced by Rabinow in 1948 [2], where he observed that MR fluids are responsive to magnetic fields. Upon exposure to an external magnetic field, MR fluid undergoes an instantaneous transition from a viscous state to a semi-solid state, forming chain-like structures whose yield strength is adjustable depending on the magnetic field's direction. Remarkably, MR fluids exhibit operational versatility within a temperature range of 40 ºC to 150 ºC, with only minor fluctuations in yield stress.
