On the Yield Stress of Magnetorheological Fluids [PDF]

open access: yesChemical Engineering Science, 2022
Magnetorheological fluids (MRFs) are a category of functional materials that exhibit magneto-mechanical coupling. These materials exhibit a reversible and instantaneous change from a free-flowing Newtonian fluid to a semi-solid state upon application of a magnetic field.

A Smart Fluid-Hydraulic System Based on MRF Valve Control and Its Application in Flexible Grasping. [PDF]

open access: yesAdv Sci (Weinh)
This study introduces a smart fluid hydraulic system using MRF valve control for flexible gripping. An MRF‐MSV with an integrated excitation coil and micro‐textured damping channels is designed and validated; micro‐texturing increases hydraulic resistance. Coupled with a soft actuator, the MRF‐MSV enables dynamic bending and grasping.

Macroscopic two-fluid effects in magnetorheological fluids [PDF]

open access: yesPhysical Review E, 2020
We investigate macroscopic two-fluid effects in magnetorheological fluids generalizing a one-fluid model studied before. In the bulk of the paper we use a model in which the carrier fluid, with density ρ_{1}, moves with velocity v_{1}, while the magnetic component (density ρ_{2}) and, therefore, the magnetization and the magnetic-field-induced relaxing

Control of transtibial prosthetic limb with magnetorheological fluid damper by using a fuzzy PID controller

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2018
The damping characteristic of a healthy limb changes throughout the gait cycle. However, for amputees who are wearing mechanically passive damping prosthesis, the lack of ability to change the damping values might expose them to injuries and health ...
