Comparison of axial and radial flux piston designs for vehicular applications with MR damper

Abstract

Improvements on suspension systems has been the eye of researchers past few decades as semiactive and active suspension systems put forth a new level of possibility for varied damping force providing a better stability to the system. Magnetorheological (MR) suspensions provide an effective replacement for passive suspension due to controllable damping force and its cost effectiveness when compared to active suspension. Different damper designs provide variable damping force in MR dampers due to the variation in the magnetic flux depending on the piston core. This work compares with two different magnetorheological piston designs namely Axial and Radial, in design, flow of magnetic flux lines and its characteristics based on damping force, velocity and current. © 2023 Author(s).
