Tribological performance of a magneto-rheological suspension

Boundary lubrication of magnetorheological fluids in PTFE/steel point contacts

“…The understanding of the tribological behaviour of these fluids is far to be complete in spite of its importance [4][5][6][7][8][9]. In many applications, dispersed iron microparticles have a typical size of the same order of magnitude as the gap thickness.…”

Optimal Design Methodology of Magnetorheological Fluid Based Mechanisms

“…The effect of centrifuging at high rotational speeds and the subsequent sealing problems associated with it can be mitigated by the proposed model. Extraordinary features of the direct shear mode like simplicity, fast response, simple interface between electrical power input and mechanical power output using magnetic fields, and controllability are features that make MRF technology suitable for many applications such as dampers, brakes, clutches and polishing devices [56][57][58][59].…”

Design and application of magneto-rheological fluid

“…There are basically three components in an MR fluid: basic fluid, metal particles and stabilizing additives [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…The metal particles are usually made of carbonyl iron, or powder iron, or iron/ cobalt alloys to achieve a high magnetic saturation. The amount of metal powder in MRF can be up to 50% by volume [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The particle size is in the μ−meter range and varies depending on the manufacturing processes.…”
