Development and Performance Analysis of Magnetorheological Fluid Clutch

This technical report presents the development and performance analysis of a Magnetorheological (MR) fluid clutch, focusing on its torque capacity and response time. The study employs a simulation technique using COMSOL Multiphysics 5.3a to analyze the MR clutch's design and operational characteristics. The theoretical torque transmission capacity is derived using the Bingham-Plastic constitutive model, while performance analysis is conducted through simulation results. The report details the two-dimensional axi-symmetric geometry used for magnetic field and computational fluid dynamics studies, highlighting the relationship between torque developed in the MR clutch and applied coil current. The MR fluid is characterized as a non-Newtonian fluid, and its flow is simulated under laminar conditions. The governing equations for magnetic fields and laminar flow are outlined, and the results are presented graphically, including surface plots and line graphs. The findings contribute to the understanding of MR fluid behavior in clutch applications.
