Magnetorheological Fluid Filled Spring for Variable Stiffness and Damping: Current and Potential Performance

Frontiers in Materials, 2022
Magnetorheological (MR) fluid is a smart material utilized for semi-active damping devices thanks to its ability to become viscoelastic solid under a magnetic field and provide variable damping.

Magnetic Spring Device

, 2009
A cylindrical system is proposed that will store magnetic energy in a localized azimuthal field that can then be quickly released on Alfvenic timescales, accompanied by the formation of a flowing Z-pinch plasma. The magnetized plasma is MHD in character and will have unilateral axial momentum with Alfvenic speeds.
