Magnetorheological dampers

Definition

Magnetorheological dampers are advanced mechanical devices that utilize a fluid containing magnetorheological (MR) particles, which change their viscosity in response to an applied magnetic field. This property allows these dampers to adjust their damping characteristics in real time, enhancing vehicle performance and ride comfort. Their adaptability makes them ideal for use in vehicle dynamics and suspension systems, where varying road conditions require quick adjustments to maintain stability and control.
