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.
