Design of a New Inside Multi-Coils Clutch for Knee-Exoskeleton Structure Based On Helmholtz Phenomenon and Magneto-Rheological Fluid

초록

Magnetorheological (MR) fluid is smart material that behaves differently with an applied magnetic field. MR brake consists of the fluid with a magnetic source to produce sufficient torque for the braking application. This paper takes the multidisc MR brake with a new approach to produce more uniform magnetic field using the Helmholtz coil setup and placing the other coils inside of the braking discs. The system is optimized for the resulting torque that can be used within the leg exoskeleton for walking support.
