Testing and Evaluation of Linear Shear Mode Magnetorheological (MR) Damper Based on Rheological Properties of MR Fluid

CODEN: JTEVAB

Abstract

Magnetorheological (MR) fluid exhibits variable yield stress and viscosity with the magnetic field, which is why it is classified under smart materials. Because of its controllable properties, MR fluid has many applications. The most common application of MR fluid is MR fluid damper. According to the flow of MR fluid, three types of dampers are possible; flow mode, squeeze mode, and shear mode. In this article, rheological properties of MR fluid, which has a high Bingham number (ratio of MR force on-state to off-state), are synthesized and the MR properties are studied. Based on these properties, a linear shear mode MR damper is designed and evaluated for its performance. A unique model is adopted to evaluate the performance of MR damper. In this model, the dimensionless Mason number is applied to establish the relation between test data of damper and rheological properties of MR fluid. This is verified for two different volume fractions of magnetic particles in MR fluid.
