| In order to meet the requirements of the magnetic field required by the yield stress test of magnetorheological fluid, this paper proposed three kinds of magnetic circuit schemes for different magnetic sources, which were permanent magnet type, current exciting mode and compound mode. The material and size parameters of each part of the magnetic circuit were determined.The finite element software was used for modeling and simulation calculation, and the magnetic induction line and the magnetic flux density were analyzed.The results show that the compound magnetic circuit is more efficient and energy saving, which is the optimum design scheme of magnetic circuit. The designed device can meet the test requirement of the magnetic field, which establishes the foundation for the construction of the experimental platform and the development of the experiment. |
