A Rheological Model for Magneto-rheological Fluids
Magneto-rheological fluids (MRF) are suspensions of particles which can be magnetized. MRF exhibit fast, strong and reversible changes in their rheological properties when a magnetic field is applied. A commercially available damping system that takes full advantage of the controllable technology of MRF and delivers valveless damping control appeared on passenger vehicles in 2003. Further comme...
متن کاملReview on magneto-rheological fluid and its application
Magnetorheological fluids have received widespread attention as smart materials due to their tunable properties. MRF consists of three key components including, soft magnetic particles, carrier liquids, and additives. This review details the characteristics, composition, and rheological principle of MRF, working principle of MRF devices, and their applications in other engineering arenas. The a...
متن کاملMagneto-Rheological Damper Modelling
A comparative analysis of different models of a Magneto-Rheological (MR) damper was done. Three models were tested: a non-linear ARX, a semi-phenomenological and a phenomenological. Although the non-linear ARX model shown the best result, this is a black-box model with limited use. However, the Semi-Phenomenological model represented an excellent option considering the physical meaning of its p...

متن کاملResponse of a Magneto-Rheological Fluid Damper Subjected to Periodic Forcing in a High Frequency Limit
We explored vibrations of a single-degree of freedom oscillator with a magnetorheological damper subjected to kinematic excitations. Using fast and slow scales decoupling procedure we derived an effective damping coefficient in the limit of high frequency excitation. Damping characteristics, as functions of velocity, change considerably especially by terminating the singular non-smoothness poin...
