Abstract

This study presents the design, modeling, fabrication, and experimental validation of a novel magnetorheological (MR) damper incorporating stationary electromagnetic coils wound around the outer surface of the damper cylinder - departing from the conventional piston-mounted configuration. This innovative arrangement overcomes the limitations of localized magnetism and variable wire lengths caused by piston motion, ensuring a uniform magnetic field along the entire piston stroke. The external coil placement also eliminates the need for a hollow piston rod and streamlines electrical routing. Computational fluid dynamics (CFD) simulations were performed to evaluate magnetic field distribution and fluid flow behavior. Experimental tests on a custom - designed rig demonstrated a tunable damping force ranging from 731.54 N (at 0 A) to 1591.47 N (at 0.2 A), corresponding to damping coefficients of 4.65 kNs/m and 10.13 kNs/m, respectively. Compared with conventional viscous dampers, the proposed MR damper offers superior tunability, a broader performance range, and simplified construction. These advantages make it a promising candidate for semi-active suspension systems in automotive, seismic mitigation, and defense applications.
