Original Abstract

The article deals with Magnetostatic analysis of a magnetorheological (MR) clutch. The analysis is needed for acquiring information about magnetic saturation of iron parts in operation mode. This paper describes a comparison of FEM model and experimentally measured data in the clutchs working gap filled with the air. The most important parameters such as use of linear and nonlinear material (iron parts, MR fluid), element type and size, effect of measuring groove for Hall sensor on magnetic field distribution, which significantly improved the FEM model of the simulation were determined, and they are also mentioned bellow. Simulation based on the verified FEM model of magnetic circuit with MR fluid was completed. Results showed places, where it is possible to reduce the material without any changes to the magnetic flux density in the working gap. With this knowledge, we reduced the weight by 13,2%.
