Abstract
Magnetorheological valves are important components in hydraulic systems that provide precise position con-trol. At present, the low-pressure drop performance of magnetorheological valves is the main problem limiting their application. To improve the pressure drop performance of magnetorheological valves, a hybrid magnetic source disc magnetorheological valve is proposed. The magnetic pressure drop model and viscous pressure drop model of the hybrid magnet source disc type magnetorheological valve based on the Bingham model are Derived. Magnetic field distributions in the damping channel of the hybrid magnet source disc type magnetor-heological valve are obtained by using ANSYS finite element analysis software. The mathematical model of the relationship between pressure drop and magnetic induction intensity was established using Matlab software, and the effects of parameters such as effective current, axial damping gap, radial damping gap, and coil width on the pressure drop performance of disc-type magnetorheological valves with hybrid magnetic sources were numerically analyzed. The results show that the pressure drop of the disc magnetorheological valve with a hybrid magnetic source can reach 10.9935 MPa at the current I=3A, axial damping gap ga=1 mm, and radial damping gap gr=1.5 mm. Compared with the conventional disc magnetorheological valve, the pressure drop performance of the hybrid magnetic source disc magnetorheological valve is improved by 28 %, which provides ideas on how to improve the pressure drop performance of the magnetorheological valve.
