Magnetorheological Performance of Nano Magnetorheological (MR) Fluid Based on NiFe2O4 Nanoparticles

Single cell magnetorheological fluid based tactile display

A tactile display is a programmable device whose controlled surface is intended to be investigated by human touch, as a finger is dragged over it. It has a great number of potential applications in the field of virtual reality and elsewhere. In this research, a prototype tactile display incorporating magnetorheological (MR) fluid has been constructed and investigated. Surface force responses of...

Theoretical Studies on Magnetorheological Fluid Brake

A Magneto-Rheological (MR) fluid brake is a device to transmit torque by the shear force of an MR fluid. An MR rotary brake has the property that its braking torque changes quickly in response to an external magnetic field strength. In this paper, the design method of the cylindrical MR fluid brake is investigated theoretically. The mechanical part is modeled using Bingham’s equation, an approa...

Optimal Design of Magnetorheological Fluid Damper Based on Response Surface Method

In this research, the effect of shape parameters such as number of magnet wire turns, spools, thickness of the gap, and pole length in a Magneto-rheological (MR) fluid damper is analytically investigated and the optimization of these parameters is done with response surface method (RSM) which is combined Neuro-Fuzzy method and Particle Swarm Optimization (PSO) algorithm. Since the electro-magne...

Magnetorheological Fluid for Levitation Migration Technology

The dispersed particles of magnetorheological fluid form stable chain-like clusters under the magnetic field, and show an effect of controllable flowability and shape. Based on this characteristic, using migration magnetic acted on the magnetorheological fluid, the object directional migration can be realized, and then the magnetorheological fluid forms levitation at the same time, which has li...
