“…The groove width (mm) and depth (mm) has been represented by 'W' and 'H' respectively while the clearance between the sealing faces (mm) is represented by 'C'. The design and analysis of the O-ring has been divided into two categories: (i) Unlubricated Condition and (ii) Lubricated Condition depending on whether lubrication was provided to the O-ring prior to its installation within the groove assembly [3], [4], [13]- [22], [5], [23]- [32], [6], [33]- [42], [7], [43]- [52], [8], [53]- [62], [9], [63]- [66], [10]- [12][23], [34], [42].…”

“…MR fluids are prepared by uniform mixing of micron sized magnetic particles in a carrier liquid. The micron size ferromagnetic particles are commonly used as a dispersed phase in a nonmagnetic carrier liquid such as mineral oil, silicone oil and deionized water (Sukhwani and Hirani, 2007). The high density of the ferromagnetic particles compared to that of the carrier liquid creates severe problems in the MR fluid suspension.…”

“…These electrolytic iron-based MR fluid samples exhibit considerable yield stress value under the applied magnetic field. Moreover, among the additives used, xanthan-gum-based sample has exhibited greater stability against sedimentation (Sukhwani and Hirani, 2007). Sarkar and Hirani (2013) observed that the yield strength of synthesized MR fluid increases by incorporation of oleic acid and tetramethylammonium hydroxide.…”

The novel controllable behaviour of magnetorheological (MR) fluid is the backbone of magnetorheological fluid-based finishing processes. MR fluid-based finishing processes facilitate better control over finishing forces as the stiffness of MR finishing fluid used in these processes can be controlled in accordance with the applied magnetic field and MR finishing fluid composition. Therefore, a detailed experimental investigation was carried out to find the effect of MR finishing fluid constituents on its yield stress through the Taguchi Design of Experiments. Rheological data obtained from a magneto-rheometer (MCR-102) was characterised by using Bingham plastic, Herschel-Bulkley and Casson's fluid constitutive modelling. The coefficient of regression (R 2) values of Herschel-Bulkley model were found to be best suited for all compositions of MR finishing fluid. Analysis of variance (ANOVA) has been used to find the contribution of selected parameters for improving the response characteristics. The optimized fluid has been then used for the finishing of biocompatible stainless steel AISI 316L, and the finishing results show that the average surface roughness value decreases down to 58 nm.

“…The MR brake [1][2][3][4] , MR damper 5,6) and MR clutch 7) are common MR devices. MR-fluid [8][9][10] and MR-grease [11][12][13] are two commonly explored MR suspensions in these MR devices. These suspensions have their merits and demerits, and it is essential to determine their suitability in MR devices.…”

Controllable yield strength of Magnetorheological (MR) suspensions makes them suitable brake material. MR-fluid and MR-grease are two commonly explored MR suspensions, and comparison between their performances is useful to decide their suitability in MR brake applications. The current paper presents such comparison. MR fluid and MR grease have been specially formulated. Ninety percent (weight percent) of Xanthan gum coated electrolytic iron powder has been used for synthesis of both MR suspensions. Two identical brake assemblies, one for MR-fluid and other for MR-grease have been developed. Experiments have been performed in the same operating conditions of speed and magnetic field for MR fluid brake and MR grease brake, and their performances of brake power output and amplification factor has been reported.
