Nanoindentation hardness of particles used in magnetorheological finishing (MRF).
Knowledge of the hardness of abrasive particles that are used in polishing is a key to the fundamental understanding of the mechanisms of material removal. The magnetorheological-finishing process uses both magnetic and nonmagnetic abrasive particles during polishing. The nanohardnesses of the micrometer-sized magnetic carbonyl iron and nonmagnetic abrasive particles have been measured successf...
متن کاملDesign and evaluation of a linear damper working with MR shear thickening fluids
Magnetorheological (MR) materials and shear thickening fluids are both smart material and their combination could offer both MR and ST effects. This study looks at the properties and behaviour of magnetorheological shear thickening fluid (MRSTF) in particular whilst applied as a semi-active energy absorber. A device with two forms of varying vibration control has been created and measured. The ...
متن کاملPreliminary Study of Modelling Dynamic Properties of Magnetorheological Fluid Damper
u(t) c 1 2 k 3 m f c Abstract A preliminary study was conducted to investigate numerical models that can be used to simulate the dynamic behaviour of a damper based on magnetorheological (MR) materials. Several articles presenting the results of experimental testing and mathematical modelling have been published recently. The goal for this study was to implement a selected model into the finite...
متن کاملDevelopment of Magnetorheological Finishing (MRF) Process for Freeform Surfaces
One of the newly developed methods for obtaining super finished surfaces for freeform is Magnetorheological finishing (MRF). MRF is an advanced finishing process in which the grinding force is controlled by magnetic field. The material removal in MRF is governed by the magnetorheological fluid which mainly consists of carbonyl iron (CI), abrasives particles, carrier fluids and additives. MRF pr...
