Heating effects on magnetorheological dampers
… used such as viscous, friction or tuned mass dampers; however, one of the most recent promising systems proposed is the Magnetorheological damper (MR damper). Because of their ability to be controlled and to adapt their mechanical properties by varying a magnetic field, their high damping …

An Invertible Open-Loop Nonlinear Dynamic Temperature Dependent MR Damper Model
A Magnetorheological damper is a commonly used component in semi-active suspensions that achieves a high force capacity and better performance than a passive system, without the added expense and power draw of a fully active system, all while maintaining failsafe performance. To fully exploit the …
