Magnetorheology of dimorphic magnetorheological fluids based on nanofibers

Smart Materials and Structures, 2014
We report a systematic experimental investigation on the use of nanofibers to enhance the magnetorheological (MR) effect in conventional (microsphere-based) MR fluids formulated in polyalphaolefin oil/1-octanol. Two kinds of nanofibers are employed that have very similar morphology but very different magnetic properties.

Durable magnetorheological fluid compositions

The Journal of the Acoustical Society of America, 2004
A durable MR fluid formulation is described which includes mechanically hard magnetizable particles, a carrier fluid derived from a polyalphaolefin and a plasticizer, and at least one colloidal additive such as colloidal polytetrafluoroethylene or colloidal graphite.

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.

Non‐Settling Super‐Strong Magnetorheological Fluids

Small, 2023
AbstractA magnetorheological (MR) fluid is generally called a suspension in which magnetic particles are dispersed in a non‐magnetic medium. When an external magnetic field is applied, a pseudo‐phase transition occurs within a short time to generate yield stress, and when the magnetic field is released, it returns to the suspended state.

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.

Super-strong magnetorheological fluids

Journal of Physics: Condensed Matter, 2001
Magnetorheological (MR) fluids, which can rapidly be changed from a liquid state to a solid state and vice versa by a magnetic field, have the potential to revolutionize several industrial sectors. The key issue is to enhance their yield shear stress. This paper reviews the physical mechanism and microstructure of MR fluids.

Ball End Magnetorheological Finishing Using Bidisperse Magnetorheological Polishing Fluid

Materials and Manufacturing Processes, 2014
A scheme to finish workpiece surface in nanometer range and obtain defect free surface using bidisperse magnetorheological polishing fluid (MRPF) by ball end magnetorheological finishing (BEMRF) tool is presented. Bidisperse MRPF consist of micron size CS and HS grade of carbonyl iron powder (CIP) with different volume fraction combinations within 20 ...
