The aim is to develop a new magnetorheological damper design that minimizes damping force variability with velocity.
Proposed a multi-channel bypass structure for improved damping performance.
Developed an optimization criterion based on the Bingham plastic model.
Integrated flow and magnetic circuit optimization principles.
Established a steady-state model validated through experiments.
Maximum absolute error of 183.16 N at 3 A and 0.04–4.0 m/s velocity range.
Maximum relative error of 0.186 observed at 0.1 A.
Damping force shows reduced velocity dependence, especially at high velocities.
