A brief description about designing of Magnetorheological (MR) damper are described. MR dampers are semi-active suspension devices that use MR fluids to produce a controllable damper. The mechanical properties of the suspension can be controlled by adjusting the yield stress of the MR fluid. In this book, the design development for a new mixed mode MR damper with combination of shear and squeeze working modes was carried out. The magnetic field generated by electromagnetic coils in MR damper was analyzed using finite element method. The MR damper was designed and fabricated based on the...
