Abstract

Magnetorheological fluids are used in a wide range of controlled systems. Magnetorheological fluids have found widespread commercial use, particularly in vibration control. Magnetorheological fluid (MR) is a type of intelligent fluid found in oil carriers. A magnetic field raises a fluid's apparent viscosity until it becomes a viscoelastic solid. A variable magnetic field intensity controls the fluid's yield stress when it is active. Control-based applications can be created by using an electromagnet to control the fluid's ability to transmit force. In MR fluid, more nuanced ferrofluid particles are used. Brownian motion cannot suspend MR fluid particles in the carrier fluid due to their thickness. Brownian motion suspends nano-sized ferrofluid iron particles, which reduce sedimentation and increases the performance of the Magnetorheological fluid. Dampers, brakes, bearings, pneumatic artificial muscles, optics finishing, fluid clutches, and aerospace all use magnetorheological fluid technology. The characteristics, applications, modes, and models of magnetorheological fluids are investigated in this paper. Understanding yielding, flow, and viscoelastic behavior in the presence of shearing fluxes are critical. Applications of MR fluid in various domain of engineering is discussed with examples. In a concise manner, the author discusses the utility of MR fluid experiments for active and semi-active vibration control systems.
