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%.
Czech abstract
Článek se zabývá MKP simulací magnetického obvodu magnetoreologické (MR) spojky s cílem získat informace o míře magnetického nasycení železných částí MR spojky v provozním stavu. V článku je popsána verifikace MKP modelu s experimentálně naměřenými daty v pracovní mezeře spojky v prostředí vzduchu. Dále byly vytipovány nejdůležitější body simulace, které ovlivňovaly přesnost modelu jako je použití lineárního a nelineární materiálu (ocelové části obvodu, MR kapalina), velikost a typ elementů, výběr a nastavení řešiče, vliv měřící drážky pro Hallovu sondu na rozložení mag. pole, atd. Do verifikace modelu byl také zahrnut vliv velikosti Hallovy sondy. Na základě ověřeného MKP modelu byla vytvořena simulace magnetického obvodu s MR kapalinou. Přesnou analýzou byla určena místa, kde je možné snížit průřez mag. obvodu a kde již nikoliv. Díky tomu byla snížena hmotnost MR spojky o 13,2% aniž by byla ovlivněna velikost mag. indukce v pracovní mezeře.
