Rheology of a Magnetorheological Fluid

Journal of Intelligent Material Systems and Structures, 1996
We report on experimental investigations of the rheological behavior of aqueous magnetic suspensions. The suspended particles are monodisperse colloidal polystyrene spheres which contain magnetic Fe 2 0 3 -grains.

Flow of Magnetorheological Fluids

Journal of Intelligent Material Systems and Structures, 2001
For efficiently describing the flow of magnetorheological fluids (MRFs), a feasible model based on the Bingham equation is presented. It allows the determination of rheological parameters from parameters attained with a measuring equipment working in the flow mode.

Behavior of Magnetorheological Fluids

MRS Bulletin, 1998
In the absence of an applied magnetic field, magnetorheological (MR) fluids typically behave as nearly ideal Newtonian liquids. The application of a magnetic field induces magnetic dipole and multipole moments on each particle. The anisotropic magnetic forces between pairs of particles promote the head-to-tail alignment of the moments and draws the ...

MAGNETORHEOLOGICAL FLUID FAN DRIVE FOR TRUCKS

Electrorheological Fluids and Magnetorheological Suspensions, 2007
A magnetorheological fluid (MRF) fan drive prototype for automotive truck application is designed and tested for both performance and durability. A dual concentric gap with drum rotor design is chosen to meet the required torque capacity, packaging, and mass constraints.

Scaling in the aggregation dynamics of a magnetorheological fluid

Physical Review E, 2007
We present experimental results on the aggregation dynamics of a magnetorheological fluid, namely, an aqueous suspension of micrometer-sized superparamagnetic particles, under the action of a constant uniaxial magnetic field using video microscopy and image analysis.

A BEARING APPLICATION USING MAGNETORHEOLOGICAL FLUIDS

Electrorheological Fluids and Magnetorheological Suspensions, 2002
A conventional automotive driveline center bearing (CB) consists of a roller bearing that rests on a U-shaped support, which includes a bladder formed by an elastomer, providing damping for radial vibrations between the roller bearing and the housing.

A Constitutive Equation for Magnetorheological Fluid Characterization

Journal of Phase Equilibria and Diffusion, 2005
A microstructural model of the motion of particle pairs in MR fluids is proposed that accounts for both hydrodynamic and magnetic field forces. A fluid constitutive equation is derived, from the model that allows the prediction of velocity and particle structure fields.

The Magnetorheological Fluid Damper Dynamic Model

INTERMAG 2006 - IEEE International Magnetics Conference, 2006
Magnetorheological fluids are materials that respond to an applied magnetic field with a change in rheological behaviour because the iron particles under a magnetic field cause the formation of columnar structures parallel to the applied field. These chain-like structures restrict the motion of the fluid, increasing the viscous characteristics of the ...
