Abstract
In order to solve the problem of low damping force caused by low utilization of magnetic field in traditional
magnetorheological dampers, a hybrid channel valve type magnetorheological damper with circular channel
and disk channel are proposed. The main content of this paper is to design the basic structure of mixed channel
valve magnetorheological damper. The mathematical model of damping force based on Bingham plastic
model was established from the design of magnetic circuits. The two-dimensional simulation model of MR
Damper was established by using EMAG module in ANSYS finite element analysis software, and the magnetic
circuit of mixed channel valve MR Damper was simulated and analyzed. The results show that the output
damping force of the hybrid channel valve-type magnetorheological damper is 18 KN and the adjustable coefficient
is 14.52 with the current I of 3A, the number of coil turns of 560, the axial damping gap of 1 mm and the
radial damping gap of 1.5 mm.
