Investigation of Mr Fluids in the Oscillatory Squeeze Mode
The paper summarises the results of laboratory testing of three commercially available magnetorheological (MR) fluids operated in the oscillatory squeeze mode. Tested fluids include the Basonetic 204 and Basonetic 4035 (BASF) and MRF-122EG (Lord Corporation). The oscillatory squeeze mode produces large forces at small displacements. This feature may be well utilised in fabrication of new MR dev...
متن کاملFerrofluids and Magnetorheological Fluids
Composition, synthesis and structural properties of ferrofluids and magnetorheological fluids are reviewed and compared. The similarities and main differences between the two types of magnetically controllable fluids are outlined and exemplified in the paper. Chemical synthesis and structural characterization of magnetizable fluids for engineering and biomedical applications are thoroughly disc...
متن کاملStudy on the mechanism of the squeeze-strengthen effect in magnetorheological fluids
Current magnetorheological (MR)fluids have the limitation that their yield stresses are not strong enough to meet some industrial requirements. X. Tang, X. Zhang, and R. Tao [ J. App. Phys87, 2634 (2000)] proposed a method to achieve high-efficiency MR fluids by study of squeeze-strengthen effect. But there is little report on its mechanism. This paper aims to investigate this effect through ex...
متن کاملInverse magnetorheological fluids.
We report a new kind of field-responsive fluid consisting of suspensions of diamagnetic (DM) and ferromagnetic (FM) microparticles in ferrofluids. We designate them as inverse magnetorheological (IMR) fluids for analogy with inverse ferrofluids (IFFs). Observations on the particle self-assembly in IMR fluids upon magnetic field application showed that DM and FM microparticles were assembled int...
متن کاملApparent stress-strain relationships of MR fluids under compression mode Apparent stress-strain relationships in experimental equipment where magnetorheological fluids operate under compression mode
This paper presents an experimental investigation of two different magnetorheological (MR) fluids, namely water-based and hydrocarbon-based MR fluids in compression mode under various applied currents. Finite Element Method Magnetics was used to predict the magnetic field distribution inside the MR fluids generated by a coil. A test rig was constructed where the MR fluid was sandwiched between ...
