Magnetic circuit design and optimisation of magnetorheological mount with tapered channel under the flow mode

In order to relieve saturation of magnetic flux density in magnetic circuit, the flow mode magnetorheological mount with tapered channel is designed. The influence of geometrical parameters of the damping channel on magnetic flux density and pressure drop is analysed. The key parameters have strong nonlinear relationship with magnetic field strength and pressure drop. Then, the parametric modelling of magnetic circuit structure was carried out using ANSYS software as the analysis system. The mount optimisation analysis model was built based on ISIGHT software. The optimisation results showed that the designed magnetorheological mount improved the saturation point of magnetic flux density of the damping channel, and the resulting pressure drop had good controllability.
